Cultivation techniques

The key techniques for the cultivation of rare medicinal herbs are mainly from the following aspects: selection of land, breeding, planting, management and pruning, and prevention of pests and diseases. The key technologies of each link are described below for reference by the majority of farmers.

First, the choice of land: wolfberry is a strong positive shrub planting, cold, drought, alkali and barren. It is better to plant a sandy loam soil with good drainage and high dryness. Fear of water. Mushi organic fertilizer 5000 kilograms, diammonium 15 kilograms, it is best to deep loose 32 cm and fertilizer mix.

Second, nursery:

1. Seeding: Use 200-300 grams per acre. Pre-plant seedlings with carbendazim and other pesticides to prevent blight, such as bed seeding, row spacing 20-25cm, ditching, ditch depth 2-3cm, Cover 1.5 cm after sowing, and then keep the bed moist.

2. Cuttage: Spring-selected mature disease-free shoots, cut into 10 cm long, immersed in clean water and used as a backup, poured water over the membranes after a good place, and insert the shoots under the membrane in a distance of 20×80 cm. First, the ground exposed two sections, leaving only one bud after emergence. (If sowing is best, soaking seeds at 40°C for 24 hours before sowing)

Third, the colonization: If you receive the net vegetable (sell leaves) market, row spacing is 2 × 0 郾 5 meters, such as the production of medlar for the purpose, but also in shaping, 2 × 1 郾 2 meters. If the fruit production is not shaped, the previous output can be 2×2郾5 meters, and 2 to 3 plants per hole. A lot of early stage auxiliary support without shaping.

Fourth, management and pruning: young branches and leaves a large amount, often inclined or lodging, can be buried to maintain dry, can also be tied with wooden poles. After planting, the saplings must be reshaped. From 4 to 5 cm away from the ground, 4 to 5 strong branches should be left, and the rest should be cut off. When the new branch grows to 30 centimeters in length, 20 centimeters is cut off, and when the collaterals grow to 30 centimeters in length, 20 centimeters is cut off again, so that the basic skeleton has been formed. To prune trees, sweeping branches, sick branches, and weak branches should be frequently removed. The excessively long branches of the branches are removed from the base, and the absurd branches of the missing branches are topped and slowly laid to form the result branches. It is also possible to remove one half of the branches and promote the side branches to fill the void. The general principle is that the density distribution is uniform and reasonable, ventilation and light transmission, long and short cuts must not only result in multiple results, but also long trees.

V. Pest control: The black fruit disease occurs in the rainy season, and the affected fruits, flowers and buds turn black. Prevention and treatment: remove diseased flowers, diseased fruits, and control with desenom zinc or with special spraying. Locust, mainly damage leaves and shoots, prevention and control: sprayed with 40% dimethoate 1000 times.

Six, harvesting and processing: fruit mature from July to October, can be followed by picking, should be light and put. Can also be spread under the tree plastic sheeting, shaking the branches so that ripe fruit fall down, the fruit thickness can not exceed 3 cm, can not be turned by hand, or black, early fruit picking can not be sun exposure under the hot sun until the wrinkled skin See the sun drying in the late sun, until the water drops to 12%, can only be sealed up. Conditions can also be dried, the effect is better, the fresh fruit's dry rate is 3 to 4:1, per mu produce about 300 kg of dried fruit.
