The difference between crisp plum and bee sugar plum: Brief introduction of bee sugar plum, characteristics: young trees are strong and straight, adult trees are more open, trees are semi-circular, with high germination rate, low branching rate and long internodes; Annual branches are sunny and brown, shady and green, and perennial branches are grayish brown; The meat is delicate, crisp and refreshing, the juice is sweet, and the quality is excellent.

Green plum, April plum, (early maturity): it matures in late June, with bright cyan before maturity and slightly bright cyan after maturity. The weight of a single fruit is about 1-2, and there is a small amount of fruit powder on the fruit surface. It tastes crisp, slagging off, sweet and sour, and has a high market price, which is well received by consumers and can be developed everywhere.

Are Tie Guai Li and Li Banbi the same person? Tie Guai Li is one of them, and half of Li is from the novel Tomb-robbing Notes of Nanpai's uncle, one of the nine magistrates (the old nine gates), ranking third among the three. The real name is unknown. When I was robbing a tomb, my leg was broken by my companion and sealed in an ancient tomb. After I escaped, I was only half dead. From then on, I became cruel and extremely suspicious. Especially after his recovery, he found several accomplices who harmed him at that time, broke their legs one by one, dragged them to the ancient tomb where he was staying, and starved to death in the ancient tomb. ...

Are wasps, wasps and wasps one species? Yes, wasps, whose scientific name is wasp, are very toxic. The venom of its stinging needle contains phospholipase, hyaluronidase and a kind of protein called antigen 5, which should be treated in time after being stung by wasps.

Cultivation techniques of plum: shaping and pruning

1, tree

The shape of plum trees often adopts natural joy shape and double-layer evacuation joy shape. The naturally open heart has the characteristics of ventilation and light transmission, high fruiting rate of inner cavity and lower branches, long service life and easy management. Double-layer open-heart tree structure, the first layer has three main branches with a spacing of about 80 cm, and the second layer has two main branches, which are happy when they fall on their heads.

Young tree stage

① Plum trees are naturally happy: cut dry at 40~60 cm from the ground in the year of planting. The first bud under the incision should face the wind direction (southwest) and the incision should be inclined. The total plane on the inclined plane is higher than the bud tip, and the lower part of the inclined plane is even or slightly higher than the bud base. In the spring of the following year, select 3~4 branches distributed around the new branches as the main branches (if it is not enough, you can choose next year). The angle and distance between the main branches are shown in the figure. If the branch angle is unreasonable, it can be corrected by pulling branches or hanging branches. Loosen the branches that are too dense, leaving the branches that are not dense as auxiliary branches. According to the growth of each main branch, it should be appropriately shortened, and 1/4~ 1/3 of the total length should be cut off. Pruning in the spring of the third year, selecting 1 angle on each main branch, taking the vigorous branch as the long branch of the main branch, cutting off the whole branch by about 1/2, and selecting the outward growing 1 ~ 2 branch as the side branch at the lower part of each main branch, and cutting off about 1/3. Try to keep branchlets less than 5 cm on the main branches, cultivate them into short fruit branches or bouquets, and cut the medium and long fruit branches appropriately. After 3~4 years, the tree shape has been basically determined, and the pruning method of the main and lateral branches will be the same as the previous year.

② Plum tree with double-layer evacuation heart shape: This tree shape is suitable for varieties with strong growth potential and upright tree potential. The stem height in the year of planting is 40~60 cm. In the spring of the following year, the vertical branches with strong growth potential at the top are selected as the trunk, and then 3-4 branches with good angles are selected as the first layer of main branches, with a short saving of 1/3, and the angle between each main branch and the trunk is 50-60. Other relatively upright branches can be thinned, and short branches and middle branches can be left as fruiting branches. When pruning in the spring of the third year, select branches with open angles from the main branches selected in the previous year.

Stripes are used as side branches and extension branches, and then 2~3 main branches are selected as the second layer on the central trunk, staggered from the first layer, with the distance between the two layers being 50~60 cm, and the central trunk is opened at the same time. The pruning methods of other branches are the same as those of nature. It can be formed in 3~4 years.

? Li miao's full fruit period

Branches of the trunk are often changed to control the size of the tree. The upper branches and peripheral branches should be combined with thinning and shrinking, that is, sparse and sparse, strong and strong, and the rest branches should be slowly released and not cut, and then shrunk at suitable branches in the next year to reduce peripheral branches, improve the lighting conditions in the inner room and lower layer, and alleviate the growth potential of the upper and outer parts of the crown. We should spare the fruitful branches while retaining the strong ones, discard the old ones and retain the new ones, and step by step in a planned way. Sparse and over-dense branches, crossed branches, diseased branches, twigs, etc. , in order to preserve nutrients and ventilation.

Are toads and frogs the same species? Compare skin and body colors.

Frog has two longitudinal folds from the back of eyes to the base of hind limbs, which are golden yellow or light brown. There is a faint longitudinal stripe in the middle. There are many rows of black stripes on the hind limbs. Frog's back is brown or yellow-green, and its abdomen is white. Toads have rough skin and are covered with warts of different sizes. The back is dark brown and the abdomen is milky yellow.

2. It is observed that toad venom glands are rich, which can be divided into skin glands and retroauricular glands. Skin glands are distributed on the back of the body, and the epidermis is locally thickened into "wart granules". The posterior auricular gland is located above the cephalic tympanic membrane. Puncture the retroauricular gland carefully with a needle, and milky toxic serous fluid will flow out. Frogs have no poison glands.

3. Observe that the male frog has a pair of sound sacs behind his mouth. When vocalizing, the gas in the mouth is pressed into the vocal sac, making it swell into a ball, while the female frog has no vocal sac. Toads, on the other hand, have no voice sacs.

Compare teeth and tongue.

Frogs have a row of tiny maxillary teeth on the maxillary edge; There are also two parallel rows of small tumor-like protrusions on the vomer at the top of the mouth, which are called vomer teeth. On the other hand, toads have no teeth. Pull out the frog's tongue, its tip is forked; Toad's tongue is not forked.

5. Observe the connection between ureter and cloaca. The frog's two ureters are connected to the cloaca, and there are two openings in the wall of the cloaca. However, toad's two ureters first converge into a common ureter, and then enter the cloaca. There are only 1 openings in the cloacal wall.

6. Observe the connection between fallopian tube and cloaca. The frog's two fallopian tubes are also connected to the cloaca. Toads, on the other hand, fuse first and then communicate with cloaca.

Compare shoulder straps

The two upper coracoid bones of the frog are closely connected in parallel, do not overlap and cannot move alternately, which is called the fixed chest shoulder strap; On the other hand, the upper coracoid bones on both sides of toad overlap each other and can move alternately, which is called arc chest shoulder strap. In front of the inner ends of the two collarbones of the frog, there is a rod-shaped shoulder sternum, and there is a semicircular cartilage in front of the shoulder sternum, which is the upper sternum. Toad doesn't have these two bones.

8. Comparison of Vertebrate Frog The first seven vertebral bodies are all cylindrical, with concave front and convex back, which is called anterior concave type, and the eighth vertebral body is double concave type; However, the first eight vertebrae of toad are concave.

The cuticle of toad is keratinized, so it is drought-resistant and can move in a dry environment far from water. Although frogs and toads have different body colors, they have protective effects in different living environments, and there are great differences under the influence of the environment. The jumping ability of toad is far less than that of frog, but the poisonous glands protect it from being swallowed by carnivores to some extent. Such organs are protective organs. The male frog has a pair of vocal sacs, which are vocal organs. Frogs' maxillary teeth are all of the same type. These teeth have no chewing function, just to prevent small animals from slipping out of their mouths. The existence and position of teeth, whether the tip of the tongue is forked, and the types of shoulder straps and vertebral bodies are all the basis for the classification of tailless amphibians. The differences between the ureter, fallopian tube and cloaca of frogs and toads are often neglected in anatomy.

The prospect of plum planting is not great, and the planting technology of plum is shaping and pruning.

Young tree stage

① The natural joy of plum trees: when planting in the same year, cut and fix them at 40-60 cm from the ground.

The first bud under the incision should face the wind direction (southwest) and the incision should be inclined.

The total plane on the inclined plane is higher than the bud tip, and the lower part of the inclined plane is flush or slightly higher than the bud base.

In the next spring, choose 3-4 branches distributed around as the main branches (if it is not enough, you can choose next year).

The angle and distance between the main branches are shown in the figure. If the branch angle is unreasonable, it can be corrected by pulling branches or hanging branches.

Loosen the branches that are too dense, leaving the branches that are not dense as auxiliary branches.

According to the growth of each main branch, it should be cut short, and 1/4- 1/3 of the total length should be cut off.

Pruning in the spring of the third year, selecting branches with an angle of 65,438+0 from each main branch, taking vigorous branches as long branches of the main branch, cutting off about 65,438+0/2 of the whole branch, and selecting 65,438+0-2 branches growing outward from the lower part of each main branch as side branches, and cutting short about 65,438+0/3.

Try to keep branchlets less than 5 cm on the main branches, cultivate them into short fruit branches or bouquets, and cut the medium and long fruit branches appropriately.

In this way, after 3-4 years, the tree shape has been basically determined, and the pruning method of the main and side branches will be the same as the previous year.

② Plum tree with double-layer evacuation heart shape: This tree shape is suitable for varieties with strong growth potential and upright tree potential.

Other relatively upright branches can be thinned, and short branches and middle branches can be left as fruiting branches.

When pruning in the spring of the third year, select branches with open angles from the main branches selected in the previous year.

Stripes are used as lateral branches and extended branches, and then 2-3 main branches are selected as the second layer on the central trunk, staggered from the first layer, and the distance between the two layers is 50-60 cm. At the same time, open and close the center trunk.

The pruning methods of other branches are the same as those of nature.

It can be shaped in 3-4 years.

Bee honey plum tree technology plum trees are generally divided into autumn planting and spring planting. Autumn sowing is carried out after defoliation and before soil freezing. The advantage is that the wound can heal and send out fibrous roots in the same year, and it can take root in time in the next spring, that is, the seedling stage is short, the survival rate is high and the growth is good. It is suitable for planting in autumn in areas where there are many autumn rains and drought in spring, but attention should be paid to cold protection before the arrival of severe winter to avoid dehydration and freezing injury in winter. Spring sowing should be planted after soil thawing and before seedling germination, and it is best in areas with irrigation conditions. In addition, in Northeast China, Northwest China, North China and Inner Mongolia, spring sowing is the best because of the short frost-free period and severe winter. The methods of digging planting pits in summer and autumn, storing rain and snow and planting in spring can be adopted, which not only has a high survival rate of plum trees, but also saves the cold protection work of newly planted young trees. In normal years, it germinates in early February and blooms in early March. The flowering period is about 15 days, and the fruit matures in late June. The fruit growth period is about 125 days. 165438+ 10 began to shed leaves in late October, and the annual growth period was about 280 days. Suitable planting area: the planting area below the altitude of 1200m in Guizhou Province, with a relatively small distribution range, mainly in Zhenfeng County, Guizhou Province. Due to the strong support of local * * *, this variety has been greatly promoted and will be more widely distributed in the future.
