Lycium barbarum is a strongly positive eggplant shrub, which is cold-resistant, drought-resistant, alkali-resistant and barren-resistant. It is best to plant sandy loam with fertile, dry terrain and good drainage. In case of stagnant water, apply 5000 kg of organic fertilizer per mu, diammonium 15 kg, preferably 32 cm deep ploughing, and mix it with fertilizer evenly.
Second, raise seedlings.
1, sowing
Use 200-300g seeds per mu, and seed dressing with pesticides such as carbendazim before sowing to prevent damping-off disease. When sowing in bed, the row spacing is 20-25 cm and the ditch depth is 2-3 cm. After sowing, cover 1.5cm, and then keep the bed soil moist.
Step 2 cut
In spring, select mature and disease-free branches, cut them into 10 cm long, soak them in clear water for later use, cover them with water, insert the branches into the lower part of the film, with a spacing of 20×80 cm, and two nodes are exposed on the ground, leaving only 1 strong buds after emergence. (If sowing, it is best to soak the seeds at 40℃ for 24 hours before sowing).
Third, colonization.
If the clean vegetables (selling tender leaves) are listed, the plant spacing is 2× 0.5m, and the purpose of producing Lycium barbarum can be 2×1.2m. The fruit of Lycium barbarum is not reshaped, and the early yield can reach 2× 2× 5m, and 2~3 plants are planted in each hole. Early auxiliary support of an unshaped plant.
Fourth, management and pruning
Young branches and leaves are large, often inclined or lodging, and can be buried in the soil to keep dry or tied with wooden poles. After planting, the young trees should be reshaped, leaving 4~5 stout branches 40~50 cm from the ground and cutting off the rest. When the new branches grow to 30 cm, cut 20 cm, and when the lateral branches grow to 30 cm, cut 20 cm again, so that the basic skeleton has been formed.
When pruning a tree, you should regularly remove the swept branches, weak branches and cross branches. The overgrown branches should be thinned from the base, and the overgrown branches in the missing branches should be topped and released slowly to form fruiting branches, or half of them should be cut off to promote the formation of lateral branches. The general principle is that the density distribution is even and reasonable, the ventilation is transparent, and the long and short sections are combined, so as to bear more fruits and grow trees.
Five, pest control
1, black fruit disease
During the rainy season, damaged fruits, flowers and buds will turn black.
Prevention and treatment
Remove diseased flowers and fruits, and spray zinc or bactericide.
2. Aphids
It mainly harms leaves and new shoots.
Prevention and treatment
Spray with 40% dimethoate 1000 times.
