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;
