How to choose Sanhong honey pomelo
When we choose Sanhong honey pomelo, we should first choose the one with plastic film and foam packaging, because Sanhong honey pomelo is a tropical fruit, and it takes a long way to transport it from other places. If it is not well kept, it is easy to cause water loss, so choose one with better sealing.
When we choose Sanhong honey pomelo, we should also look at whether the outer surface of Sanhong honey pomelo is damaged or moldy, and the outer surface of Sanhong honey pomelo should be smooth and wrinkle-free. If there are no wrinkles and the surface is smooth, it means there is more water. If there are many wrinkles and moldy phenomena, it means that Sanhong honey pomelo has been placed for a long time, which is easy to breed bacteria. When we choose, we must choose the one with smooth outer surface and no mildew.
We should choose the size of Sanhong honey pomelo according to our own needs. If we have many families, we have to choose a big one. If we have few families, we have to choose a slightly smaller Sanhong honey pomelo. If there are many people in the family, you can't separate the small ones. If there are few people at home, you can't eat it all at once, which is easy to breed bacteria.
When we choose Sanhong honey pomelo, we still have to press the outside of Sanhong honey pomelo with our hands. If you press it by hand on time, it feels hard, indicating that Sanhong honey pomelo is thin and fleshy. If you touch it by hand on time, it feels soft and blistered, indicating that Sanhong honey pomelo has thick skin and less pulp. When we choose Sanhong honey pomelo, we should buy thin-skinned pomelo.
When we choose Sanhong honey pomelo, we should also look at the weight of Sanhong honey pomelo. If the small three red honey pomelo is heavy after weighing, it means that there is a lot of water, and such a small three red honey pomelo will feel very sweet. If the big Sanhong honey pomelo is very light after weighing, it should not be considered as easy to buy and sell. In fact, this three-red honey pomelo has been stored for a long time, and the water has evaporated, making it feel dry and tasteless.
When we choose Sanhong honey pomelo, we should consider all aspects comprehensively, not just unilateral factors. When we choose Sanhong honey pomelo, we should not only look at the size of Sanhong honey pomelo, but also look at its water content, skin thickness and freshness. In addition, when we buy Sanhong honey pomelo, we try to buy honey pomelo and crystal pomelo. Personally, I think these two kinds of Sanhong honey pomelo are sweet and delicious.
Planting methods and techniques of Sanhong honey pomelo
Land selection
Pinghe Yuanmanfeng Sanhong Pomelo should be built in a place (far from the industrial zone) that is sheltered from the wind and sunny, with deep soil layer, good drainage, loose and fertile soil, sufficient water, convenient transportation and no environmental pollution. Mountainous areas should sit on the gentle slope of low mountains with a slope below 25 degrees and north to south.
According to different gardens, rationally plan communities, roads, septic tanks, pools and drainage systems, and make good preparations before planting, such as soil preparation, pit digging, base fertilizer application and soil improvement.
Apply plantar fertilizer
Apply 40-50 kg of pigsty fertilizer or cow dung 15 kg (commercial organic fertilizer can also be used), calcium magnesium phosphate fertilizer 1 kg, 0. 5 kg compound fertilizer per hole. Mix the fertilizer and topsoil thoroughly to form fertile soil, and add a little lime. Then, put the fertile soil back into the hole and pile it into a circle with a diameter of 1500px higher than the ground.
Planting quality directly affects the growth and 1 fruiting time after planting. In order to improve the quality of planting, the orchard needs to implement unified planning, contiguous planting, alternate arrangement according to a certain row ratio and reasonable close planting. The planting technology of Sanhong honey pomelo is close to that of traditional honey pomelo, so it is advisable to use large seedlings for planting.
Planting time and specifications
To select good varieties and strong seedlings, the leaves of pomelo seedlings should be complete, thick and dark green, the roots should be complete, the leaves and roots should be free from pests and diseases, and the yellow-leaf pomelo seedlings should not be selected. It can be planted after each new branch grows and before the next new branch grows. Generally speaking, spring planting should be done after the spring shoots are ripe (it is advisable to plant spring shoots in Zhixia before they are picked) or autumn planting should be done after the autumn shoots are ripe (about 10 month). The plant spacing is 3m × 3m in mountainous area (60 plants per mu) and 3m × 4m in flat land (50 plants per mu).
Planting method
Classify seedlings according to size, plant seedlings at the same level together, cut off long roots and dense branches, keep 3-4 main branches, and plant roots with soil. When planting, the rhizosphere soil should be carefully excavated, and the root groups should extend in all directions. After covering the soil, lift the seedlings up slightly, and cover them with fine soil after practical use. After planting, spray foot water and cover it with weeds or straw to ensure survival. Water 5 days after planting and 6 days after rain. Generally, chemical fertilizer should not be applied within 1 month after seedling planting.
After planting 1 month, topdressing should be done in time according to the growth of seedlings, but only thin and decomposed organic fertilizer or nitrogen, phosphorus and potassium compound fertilizer can be topdressing to prevent new roots from being damaged. After that, topdressing 1-2 times a month, and the concentration can be gradually increased. Young trees mainly apply nitrogen fertilizer, so as to apply it frequently and thinly.
The surviving young trees should be cut from the height of 1250px above the ground to promote the generation of new shoots, then leave 3-5 new shoots growing in different directions and evenly distributed as main branches, and then cultivate 3 auxiliary branches on the main branches, and cultivate corresponding side branches on the auxiliary main branches. The length of each branch should be 15-575 px, and the angle is not enough.
Sufficient fertilizer should be applied before each shoot, and attention should be paid to bud control and shaping at each shoot picking stage to promote the germination of new shoots to be more tidy and robust, so as to achieve the purposes of crown expansion, early fruiting and high yield.
After two years of planting, the lateral trunk shape is adopted uniformly, and the methods of supporting, pulling, hanging and controlling buds are adopted to make the crown ventilated and transparent, with many bore holes and thick mother branches. According to the growth trend of trees, increase nutrient accumulation in branches and promote early fruiting.
Fertilization principle
Advocate the application of more organic fertilizers and rational application of inorganic fertilizers. And according to the leaves, orchard soil, honey pomelo phenology and other guidance fertilization. Fruit trees do not need chlorine fertilizer.
Fertilization method
Mainly based on soil fertilization, combined with foliar fertilization. The methods of annular furrow application, strip furrow application, hole application and soil surface fertilization were adopted. Reasonable fertilization can meet the needs of pomelo trees for nitrogen, phosphorus, potassium and other elements, and achieve the purpose of early fruit, high yield and high quality.
Apply quick-acting fertilizer before spring shoots germinate to promote spring shoots to come out earlier and more. In order to promote the number and uniformity of autumn shoots, the amount of nitrogen fertilizer should be increased before shooting, and phosphorus and potassium fertilizer should be applied appropriately in the peak period of autumn shoots.
Apply 20-30 kilograms of pig manure to the plants to accelerate germination, and apply it from the end of February to the beginning of March.
Fruit-keeping fertilizer is mainly topdressing outside the roots, spraying sea elf biostimulant (foliar type) or 0.3% urea +0.2% phosphorus and potassium source pool.
From the end of June to the beginning of July, 20-40 kg of pig manure was applied to the plants with strong fruit and fertilizer.
Fruit-picking plants should apply 40-60 kg manure+200 g urea+0.5 kg phosphate fertilizer before and after fruit picking, usually in June+February, 5438.
