The spring tea is more protected

The post-harvest tube of spring tea is very different from that of the post-harvest spring tea. Because the tree has consumed a lot of nutrients after harvesting, if the management can not keep up, it will not only affect the yield and quality of summer and autumn tea, but also affect the yield of spring tea in the coming year. And quality. According to my field experience, the following points should be grasped after spring tea harvest:
1, a reasonable fertilizer. According to the measurement, each production of 50 kg dry tea needs about 2.5-3 kg of nitrogen, 0.9-1.2 kg of phosphorus, and 1.1-1.5 kg of potassium. Thirty centimeters between tea trees can be digged into 10-15 kilograms of urea per 667 square meters, soil miscellaneous fertilizer, pig cattle bar fertilization 3000-4000 kilograms, and apply phosphorus, potash or cake fertilizer 20-30 kilograms. If the tree vigor is weak, 0.5% urea solution and 0.2%-0.3% potassium dihydrogen phosphate solution may be sprayed on the foliage.
2, weeding weeding. The cultivating depth is about 10-15 cm, and it can be deeper at 30-40 cm away from the neck of the tea tree. The weeds can be removed by weeding and cultivating the soil to loosen the soil, increase the ability of the soil to store water and fertilize, and promote tree vigor to recover as soon as possible.
3, science pruning. The branches that were kept in the past were lightly trimmed to remove the shoots that had grown last year, leggy shoots, dead branches, diseased shoots, etc., and to retain the robust branches of the plexus in order to facilitate sprouting of the buds. For senescent tea trees, heavy trimming was required. Cut about one-half of the crown of the tea, leaving the main branch and lateral branches; or adopt the method of the Taiwanese to cut away more than 7-10 cm from the stem base, and then re-fertilize the material, strengthen management, and achieve the purpose of updating and rejuvenation. .
4, prevention and treatment of pests. The main diseases and pests of tea trees in spring include leaf blight, tea caterpillars, leafhoppers, and tea aphids. The leaf blight must be sprayed with lime sulfur and Bordeaux mixture in the whole park. 90% Trichlorfon 1000 times solution or 80% Dichlorvos 2000 times solution can be used to control tea caterpillars. The leafhopper and tea aphid can be sprayed with 40% dimethoate 2000 times solution or 25% carbofuran 1000 times spray solution.

Hawthorn contains a variety of organic acids. After oral administration, the acidity of gastric juice is enhanced, pepsinase activity is increased, and protein digestion is promoted; hawthorn acid stimulates gastric mucosa to promote gastric juice secretion; Hawthorn contains lipase, which can promote fat digestion; Hawthorn contains vitamin C and other components, which can increase appetite by oral administration; Hawthorn can regulate gastrointestinal motility, inhibit gastrointestinal smooth muscle in spastic state, and relax gastrointestinal smooth muscle. Relaxation of smooth muscle has an exciting effect.
