2. Bamboo variety garden can plant 10-50 trees.
3. Enjoy the bamboo scenery in the small garden of the garden-5-20 trees is enough. Mainly in the form of drilling, the hole depth is 30-40 cm, and the hole size is 1 m square. Or use a flowerpot with a diameter of 50- 100 cm.
Ornamental bamboo cultivation season:
Early spring and February are the best cultivation seasons for ornamental bamboo. In addition, every year from 10 to March, June in plum season is a good season for afforestation. Some landscaping projects that catch up with the construction period need to be constructed in other seasons, such as midsummer, which requires rich experience and post-plant management technology. Management of ornamental bamboo seedlings
1. Intertillage weeding: twice a year, from June to August, with a depth of 8~ 10 cm. Weeds rot and become fertilizer.
2. Fertilize and cultivate soil: Because the underground stems of bamboo are shallow, cultivate soil at the same time after weeding to prevent weeds from rotting, which is beneficial to absorption. Insufficient fertilizer, poor growth of bamboo stems, premature disappearance of new green. In order to make the garden grow strong bamboo every year, nitrogen, phosphorus, potassium, silicon fertilizer and organic fertilizer should be applied. Each clump of compound fertilizer is about half a catty. It is simple and effective to raise seedlings and cultivate soil with the functions of moisture conservation, bamboo fixation and anti-shaking.
3. Irrigation and drought resistance: ornamental bamboo likes to be warm and humid, and it needs a lot of water during the shoot emergence period, so it has the saying of "mushrooming". In case of drought during the bamboo shoot period, the newly-built bamboo forest should be watered to resist drought and strive for the early development of the young forest. In the summer of enjoying the bamboo scenery, the drought was serious, which would seriously affect the survival rate and seedling growth, and it was necessary to water to fight drought. Watering can be done in the morning and evening. Water thoroughly and cover some straw around the mother bamboo to keep moisture and cool down.
4. Thinning: After 3-5 years, some old bamboo stalks can be thinned, so that new bamboo has a spacious space to spread its branches and shape.
Management of Ornamental Bamboo after Scenery
1. Intertillage weeding: 1-2 times a year, from June to September, with a depth of 8~ 10 cm. Weeds rot and become fertilizer.
2. Fertilization: In order to make the bamboo leaves dark green, a small amount of compound fertilizer can be applied, per mu10 ~ 20kg.
3. Irrigation and drought resistance: In the midsummer dry season, bamboo leaves are easy to lose water and turn green and yellow, and need to be watered and moisturized in the morning and evening.
4. Pruning and shaping: in the middle of June of that year, Hsinchu can keep 8- 10 branches to catch the upper bamboo shoots. It can improve the ability to resist wind and rain loosening and increase the aesthetic feeling of bamboo.
5. Thinning: Thinning some old bamboo stalks, so that Hsinchu can have a spacious space to spread its branches and shape, improve the ventilation and light transmission conditions in the forest, and reduce the occurrence and harm of pests and diseases. The time is the end of May and the beginning of June every year. Autumn and winter are also fine. The scale of bamboo ash harms many kinds of bamboo with gold and jade. Adults and nymphs parasitize in the axils of branchlets, suck juice from leaf sheaths, and form grayish brown spherical wax shells in the later stage, resulting in withered branches and leaves, slow growth, and decline of bamboo bushes, which affects bamboo shoots. Adult: the female adult is pear-shaped, with a slightly sharp front end and a wide back end, all of which have induration. Spherical wax shell, diameter 1.5-2mm, purplish brown, covered with grayish brown calcareous mixed debris. Male adults are about 1.3mm long, with reddish-brown head and chest and yellowish abdomen. There are sexual spines and two tail hairs at the end of the abdomen. The 1 generation occurs in 1 year, and the fertilized female adults overwinter in the sheath of new leaves in that year; The next spring, they continued to eat, pregnant with eggs, and the worms expanded into spheres; They lay eggs under the body in late April and hatch into newly hatched nymphs in May and June. They quickly climb into the leaf sheaths of new leaves to fix and suck juice, and at the same time secrete white wax powder on the body. In late May, the male nymph climbed from the base to the end of the leaf sheath, cocooned and pupated, and emerged as a male adult in June, during which the female adult also emerged. After mating between males and females, the male adults died rapidly, and the female adults continued to overwinter in 10.
Prevention and cure method
(1) Strengthen the management of bamboo forests. Timely intertillage and loosen soil, scientifically fertilize water, rationally cut down, maintain proper density of bamboo forest, improve plant resistance and reduce pests; According to the harmful habit of the insect, it should be scraped manually, and the seriously damaged plants should be dug up as soon as possible.
(2) Protect and utilize natural enemies such as ladybugs, parasitic bees and lacewings.
(3) chemical control. During the incubation period of nymphs, spraying 25% quinalphos EC 500- 1000 times or 20% rice lice EC 1500-2000 times.
