Water-saving technology of Chinese wolfberry

Lycium barbarum is a small shrub with shallow roots. in more than 7 months of the whole growth period, the critical period of water requirement for plant growth is in late April (bud emergence of old root branches and new shoots), and the maximum efficiency period of water requirement is in late June (fruit expansion and early ripening). The masses say that Chinese wolfberry cannot do without water, so it is necessary to irrigate rationally and pay more attention to water-saving techniques in the management of the whole growth period of Chinese wolfberry. Both agricultural measures, biological regulation and water-fertilizer coupling system are adopted to promote the coordinated development of vegetative growth and vegetative reproduction of Chinese wolfberry plants, in order to obtain high quality and high yield of Chinese wolfberry fruit, reduce production input costs, and increase production and income.

1. Water-saving techniques of young Lycium barbarum

Before the establishment of the garden, ① leveled the land with a height difference of 0.3cm ~ 0.5cm, and every 0.3mu ~ 0.5mu was a field.

Before planting ② seedlings, the roots of seedlings were dipped in the mud of 100PPM naphthylacetic acid.

③ planting pits were first filled with 5 kg of rotten stable manure and mixed with soil before planting seedlings.

④ irrigated for the first time at the beginning of May, the inflow of 40 cubic meters to 50 cubic meters per mu.

⑤ cut off the sprouting sac in the rhizosphere of the seedling plant in the middle of June, cut off the overgrown branch (commonly known as Youtiao) except the main branch, and topped the main branch at the 30 cm length of the branch to promote the fruiting branch.

two。 Water-saving techniques of adult Lycium barbarum

① shallow ploughing. From late March to mid-April, the garden was ploughed 5 cm ~ 10 cm to preserve soil moisture and increase moisture. It was determined by experiment that the rows of Lycium barbarum after shallow ploughing. The average soil water content of 0 cm ~ 20 cm soil layer is 18.34%, the soil water content of non-shallow tillage is 17.78%, and the height is 0.45%; the soil water content under canopy is 18.84%, that of non-shallow tillage is 17.70%, and the height is 1.14%. The spring shoot was born 5 days earlier, and the growth increased by 1.93 cm.

② pruning. In the middle of May, the rhizosphere of the plant was cut off in time, and the overgrown branches on the main branches and main branches were cut short to reduce consumption and promote the growth of fruiting branches. According to the investigation, compared with the unpruned plants, the number of fruiting branches increased by 46, the branch length increased by 8 cm, and the fruit yield per plant increased by 0.45 kg.

③ irrigates the head water at the beginning of May, and the inflow water per mu is 50 ~ 60 cubic meters.

④ in the middle of June, the soil ditch applied nitrogen and phosphorus compound fertilizer, 250g per plant, after mixing well with the soil, closed ditch irrigation, water intake of 50 cubic meters per mu, no leakage irrigation, no series irrigation, no drainage.

⑤ leaves are sprayed with nutrient liquid fertilizer every 7 to 10 days in July, and the spraying amount is 120kg per mu. If the leaves are curled at noon, they can be irrigated at night, and the water intake per mu is about 40 cubic meters.

⑥ irrigated white dew in the first ten days of September, with a water intake of 50 cubic meters per mu to apply base fertilizer and turn the garden in autumn.

⑦ irrigation winter water in late October, 60 cubic meters of water per mu, soil water storage, plant heat preservation overwintering.

The amount of irrigation in the whole growth period of Chinese wolfberry orchard is controlled from 450 cubic meters to 500 cubic meters to 250 cubic meters to 300 cubic meters.
