Chestnut is blooming in May and new shoots are growing vigorously. Cultivation management should combine its growth characteristics and physiological needs, try to control vegetative growth, promote reproductive growth, ensure good flowers and strong fruits, in order to improve the edible quality of the fruit, and increase the commercial value of the fruit. Lay the foundation. The main points of management are as follows:
One is top dressing to supplement nutrition. Spraying 0.3% borax + 0.3% urea solution during flowering can increase the fruit setting rate. Topdressing chemical fertilizers after flowering, mainly nitrogen and boron fertilizers, generally use 2.5-5 kg ​​urea per plant for large trees and 0.25 kg per plant for young trees. The amount of boron fertilizer applied is calculated based on the projected area of ​​the canopy of 15 g/m2, and more application may cause fertilizer damage. Water should be irrigated in time after fertilization. If there is no irrigation condition, the technology of storing fertilizer water in holes can be used. In the young fruit stage, topdressing phosphorus and potassium fertilizer.
The second is emasculation to retain nutrients. When the male flowers grow to 3 to 5 cm, spray 1000 to 1300 times of sclerotyl alcohol to remove excess male flowers and save nutrients for fruit setting. Generally, 13 kg of water is applied to each vial, and the foliar spray should be uniform and meticulous.
The third is summer pruning. Thinning the branches to open the light, thinning out the long branches, over-dense branches, and thin branches in the crown, increasing the light in the inner cavity of the tree; picking the heart to promote the flowers, the results of the branch leaves 1 to 3 leaves in the front of the fruit, the male flower branches from the 10th to the The core is topped at 20 leaves, and the developing branches are topped from 13 to 18 leaves.
The fourth is the prevention and control of pests and diseases. Insect pests should focus on the control of chestnut aphid, red spider, chestnut flower moth, boat-shaped caterpillar, swing caterpillar, etc. The spraying agent should be 2000-3000 times of imidacloprid, 1600-2000 times of Nissoran, 4.8% pyridaben 1000～ 1500 times liquid, and lambda-cyhalothrin 3000 times liquid. Disease should focus on prevention and treatment of ring pattern disease and rot disease. The spraying agent should be DuPont Fuxing 8000～10000 times liquid, or ring pattern 1 800 times liquid.
The fifth is cultivating soil loosening and pressing green manure. Before the rainy season comes, plowing, mulching grass and pressing green can improve the root growth environment, increase soil organic matter content, and improve soil permeability.

Fruit juice drinks is a beverage made of fruit juice products obtained by physical methods such as pressing, centrifugation and extraction. Fruit juice retains most of the nutrients in the fruit, such as vitamins, minerals, sugar and pectin in dietary fiber. Often drinking fruit juice can help digestion, moisten the intestines and supplement the lack of nutrients in the diet.
There are two kinds of fruit juice: pure fruit juice and compound fruit juice. As far as pure fruit juice is concerned, it can be divided into two types: one is to directly use the original juice, and the other is to dehydrate the freshly squeezed fruit juice first, and then add water to reduce it into concentrated fruit juice. Most pure fruit juices are concentrated. AGOLYN offers various flavors of honey tea, such as honey Citron tea etc.
