Embodiment 1

[0054] A kind of high-quality winter jujube protected cultivation method, comprises the following steps:

[0055] (1) Selection of venue

[0056] It is advisable to choose plots with clean air and water quality, flat and open terrain, sufficient sunlight, fertile and unpolluted soil, and good drainage and irrigation conditions. Slopes, etc.;

[0057] (2) Greenhouse construction

[0058] The greenhouses are 8-span north-south greenhouses. The 8-span greenhouses have a large space, are convenient for automation and mechanization, and have a land utilization rate of up to 90%. It can be adjusted according to the length of the field. The side height of the second shed in the shed is 2.5m, the ridge height is 4.5m, the main column and the main beam are set every 4m, and the auxiliary bracket is set every 1m. Films, insect nets, windproof ropes, automatic blower fans, water and fertilizer integration and other mechanized equipment are installed in the shed;

[0059] (3) Field pr...

Embodiment 2

[0091] The difference between embodiment two and embodiment one is:

[0092] The step (3) field arrangement: 1.25 tons of commercial organic fertilizers with a total content of 5% of N, P, and K in the fields ready for planting ditch, and 35cm of rotary tillage;

[0093] Said step (6) fertilizer management: apply fruit fertilizer at the beginning of July, when the growth condition of the tree body is good, 13kg / mu of sulfur-based ternary compound fertilizer, if the tree body appears the symptom of fertilizer deficiency, can apply 2 times of water-soluble fruit fertilizer Fertilizer, the first application in early July, the second application 20 days later, each application of sulfur-based ternary water-soluble fertilizer 10kg / mu, after the fruit harvest at the end of November and early December, apply winter fertilizer once to supplement plant nutrition, sulfur-based Ternary compound fertilizer 25kg / mu;

[0094] Described step (9) adopts small-scale mechanical rotary tillage ...

Embodiment 3

[0097] The difference between embodiment three and embodiment one is:

[0098] The step (3) field arrangement: 1.5 tons of commercial organic fertilizers with a total content of 5% of N, P, and K are sprinkled on the fields ready for planting ditch, and 40cm of rotary tillage is used;

[0099] Said step (6) fertilizer management: apply fruit fertilizer at the beginning of July, when the growth condition of the tree body is good, the sulfur-based ternary compound fertilizer is 15kg / acre, if the tree body appears the symptom of fertilizer deficiency, can apply 2 times of water-soluble fruit fertilizer Fertilizer, the first application in early July, the second application 20 days later, each application of sulfur-based ternary water-soluble fertilizer 12kg / mu, after the fruit harvest at the end of November and the beginning of December, the winter fertilizer was applied once to supplement plant nutrition. The same fertilizer and fertilization method as spring fertilizer, sulfur-...

Abstract

The invention discloses a high-quality winter jujube facility cultivation method, and belongs to the field of crop planting. The method includes the steps: garden land selection; greenhouse erecting;field preparation; tree seedling planting; temperature management; nutrient and water management; tree shape trimming; fruit bearing mainstay branch alternating; bee assisted pollination; fruit thinning; intertillage and weeding; disease and insect pest control. According to the method, a special controllable small-area environment is created for fruit trees, natural rainwater is avoided, irrigation periods and irrigation volume are flexibly adjusted, the trees and the fruits can be optimally irrigated at growth and development stages, the dehiscent fruit rate of winter jujubes is reduced, thequality of the winter jujubes is improved, the commodity rate of the winter jujubes is increased, occurrence and propagation of diseases and insect pests can be effectively controlled by facility cultivation, application of pesticides is less or avoided, an effective approach is provided for production of pollution-free green fruits, fertilizers are reasonably applied, biological insecticides are reasonably used, growth and development of the fruit trees are facilitated, high-quality and high-yield winter jujubes are produced, and agricultural ecological environments are protected.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for facility cultivation of high-quality winter jujube. Background technique [0002] Dongzao belongs to Rhamnaceae, Jujube genus. It is an excellent late-maturing and fresh variety of thornless jujube. It usually matures naturally from October to November in the Gregorian calendar. Because the weather in the north is cold earlier, it is named "Dongzao". It is distributed in Shanxi, Hebei, Shandong and other places. The average single fruit weight is 17.5g, and the maximum single fruit weight can reach 25g. It is shaped like an apple and is called "little apple". The peel is reddish red and bright, the skin is thin, the meat is crisp, the meat is tender, juicy and slag-free, sweet and fragrant, and the edible rate reaches 95%. Winter jujube is not only delicious, but also very nutritious. Contains 19 kinds of amino acids needed by the human body, such as asparti...
