Cultivation techniques of Chinese wolfberry

Chinese wolfberry has long been known as a traditional anti-aging tonic. Modern medical research has found that its leaves, fruits and fruit stalks all have anticancer effects. According to the article in "Countryside know-how", the stem tip of young leaves of Lycium barbarum has been listed as a net vegetable, with an income of 5000 million yuan per mu. It has been popular in Harbin to make longevity porridge rice with Chinese wolfberry and rice. Serving as seasoning and side dishes are becoming more and more popular.

It was observed that the mature branches of Chinese wolfberry cultivated in the open field of Qitaihe and Boli for 16 years had no freezing damage, and they were planted in the same year and saw fruit in the same year.

1. Lycium barbarum is a strong positive shrub of Solanaceae, which is resistant to cold, drought, alkali and barren. Planting with fertile, high-lying dry, well-drained sandy loam soil is better, afraid of stagnant water but with irrigation conditions is better. Apply 5000 kg of organic fertilizer and 15 kg of diammonium per mu, preferably deep pine 30 cm and mix well with fertilizer.

2. Raising seedlings 1. Sowing seeds: 200 million 300 grams per mu. Before sowing, seeds are mixed with carbendazim and other pesticides to prevent blight. Such as bed sowing, row spacing 20-25cm ditching, ditch depth 2Mel 3cm, cover soil 1.5cm after sowing, and then keep the bed soil moist. 2. Cuttings: select mature and disease-free branches in spring, cut them into 10 cm long, soak them in clean water and set aside. After pouring enough water to cover the film, with a row spacing of 20 cm × 8 cm, after piercing the hole with a bamboo stick, the branches were inserted into 2x3 under the film, 2 nodes were exposed on the ground, and only one strong bud was left after emergence.

Third, planting such as harvesting clean vegetables (selling tender leaves) on the market, the row spacing is 2 meters × 0.5 meters; if you want to reshape Chinese wolfberry for the purpose, you can plant 2 meters × 2.5 meters in the early stage; each hole can also be planted with 2 meters × 2.5 meters; 3 plants can also be planted in each hole, if more than one plant is not plastic, it needs auxiliary support in the early stage.

The planting pit is 30 mi 40 cm deep and 30 mi 40 cm in diameter, allowing the roots of the seedlings to stretch in all directions and stand in the center. First backfill the topsoil mixed with organic fertilizer, and then backfill the subsoil mixed with organic fertilizer. Cover with plastic film after pouring water through.

Fourth, manage and trim a large amount of branches and leaves of young trees, which are often tilted or lodged, which can be buried to protect the trunk, or tied up with wooden poles.

After planting, the young trees should be reshaped and 5 strong branches should be left at 40-50 cm from the ground, and the rest should be cut off. When the new branch grows to 30 cm, cut 20 cm, and when the lateral branch grows to 30 cm, cut 20 cm more, so that the basic skeleton has been formed.

Adult tree pruning. Always remove sweeping branches, sick and weak branches, and cross branches. For the parts with many branches, only the long branches are thinned from the base, and the overgrown branches at the missing branches should be topped and slowly released to form a fruiting branch, or it can be cut and reserved to promote lateral branches to fill the void. The general principle is that the density distribution is uniform and reasonable, ventilation and light transmission, the combination of length and length, not only to more fruit, but also to grow trees.

Fifth, the prevention and control of black fruit disease by diseases and insect pests occurs in the rainy season, and the damaged fruits, flowers and buds turn black. Prevention and treatment: remove diseased flowers and diseased fruits, and spray mancozeb or bacilli. Aphids, mainly harmful to leaves and twigs, were sprayed with 1000 times of dimethoate.

Sixth, harvest and processing fruits mature one after another from July to October, which can be picked as they are ripe, picked and placed lightly. You can also spread plastic sheeting under the tree and shake the branches to make the ripe fruit fall and put away. The thickness of the dried fruit is not more than 3 cm, do not turn it by hand, otherwise it will turn black. First-picking fruit can not be exposed to the hot sun, until wrinkled skin can be seen in the hot sun to dry. When the moisture drops to 12%, put it away and store it. If possible, it can also be dried, and the effect is better. The dry rate of fresh fruit is 3% and 1%, and the yield of dried fruit is about 300 kg per mu.
