Lycium barbarum planting adapts to that kind of weather.

(1) Seed collection, seed preparation and seed storage The seed collection period of Lycium barbarum is from July to165438+1October. When the fruit changes from green to purple-black, it should be picked in time, registered immediately and transported to the designated place. After collecting seeds, clean and thresh them with gauze, and then filter and clean them with fine reeds. Dry in the sun or in the morning and evening to avoid exposure. Adopt the method of manual seed cleaning. Seeds are prepared and stored in fiber bags in dry and ventilated places.

(2) Determination of seed quality In addition to the quality of provenance, seed quality should also be tested for purity, 1000-grain weight, germination rate, viability, fineness, water content and weight. The most important thing is to test and determine the germination rate of seeds. This method is determined by the germination method of laboratory samples. Judging the quality of seeds according to their appearance and internal anatomy.

(3) The propagation mode is mainly seed propagation, and cutting and tillering propagation can also be used.

(4) Propagation of roots and tillers In spring, the roots and tillers around the mother plant are dug up and cultivated in the nursery.

Tiantuan management

Intertillage and weeding: after the seeds emerge, loosen the soil for weeding for 4~6 times per year/kloc-0, combined with irrigation.

Irrigation: Irrigation should be carried out according to soil moisture, generally 4-6 times per year/kloc-0.

Plant spacing: in June, when the height of seedlings is 3~5cm, the spacing between seedlings is too close. Seedlings will be fixed around mid-July, and the spacing between seedlings will be 10~ 15cm, and the superior will be removed and the weak will remain strong.

Topdressing: combined with irrigation, topdressing effective nitrogen fertilizer 1~2 times in the middle and late June and topdressing 1 time in the middle and late July.

Pest control: pests include aphids, medlar, medlar powdery mildew, coal haze and so on. It can be controlled by spraying 40% omethoate, 0. 1% liquid medicine and 0. 1% carbendazim liquid medicine.

Breeding mode

Cutting propagation: Cutting seedlings bear early fruits and can maintain the excellent characters of the female parent. Generally, after the juice stops flowing, but before germination, select 1 annual branches or stout branches with full buds on excellent plants, cut them into cuttings with a length of 18~20cm, obliquely insert the whole bed with a row spacing of 20 cm ~ 50 cm, and then compact, stably insert and water frequently.

Seed propagation: Before sowing, soak the reserved seeds in warm water at 40 degrees Celsius for 24 hours to improve the germination rate, which is generally about 90%. The sowing period is from late March to mid-April. The row spacing of drilling is 30cm, and the ditch depth is 0.5~ 1cm. The seeds are mixed with some fine sand, evenly spread in the ditch, slightly covered with fine sand, lightly pressed and watered to keep the soil moist. The soil is lightly irrigated every 1~2d/time, and the temperature is 1 7 ~ 21. Sowing amount 1~ 1.5kg/m2, seedling yield 40000 ~ 50000 plants /m2. If there is no watering condition or water source is insufficient, cover it with fine sand and soil slightly after sowing, then cover it with plastic mulch, and cover it completely with 1.5~2cm mulch to avoid sunlight penetration. Observe every day, and remove the plastic film on rainy days when the seed buds penetrate the land. This can not only effectively maintain soil moisture, but also avoid water evaporation and soil drying caused by plastic film warming. So as to solve the contradiction between deep sowing and nest bud, shallow sowing and bud burning. This method summarized in the specific seedling production is very practical for improved seed seedling in places with insufficient water resources such as plateau.
