Sand cultivation mode

Abstract

The invention discloses a sand cultivation mode, comprising the steps of setting planting ditches in a protected land, wherein the planting ditches are 0.8 m spaced, and a drain ditch 0.35 m in depthis arranged at the outer side of each planting ditch; covering the inside of the drain ditches with mulch, fixing well, and setting an underground liquid reservoir at the tail end, except for the cultivation area, of the protected land; allowing water in the planting ditches to smoothly flow from inside to outside, and covering the inside of the planting ditches evenly with HDPE (high-density polyethylene) to tightly wrap the two sides, inner side and outer side of the planting ditches; mixing well slag and sand in the mass ratio of 3:5, spreading the mixture evenly into the planting ditches,laying substrate, using water mixed with a disinfectant to irrigate the planting ditches by flooding, and washing the substrate twice; laying dripper tubes above the substrate, and covering with mulch. The sand cultivation mode has low input cost; the slag and sand can be taken in situ; the sand cultivation mode is simple to perform and is easy for common people to accept; the sand cultivation mode provides better convenience and high speed, and saves time and labor.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a yellow sand planting mode. Background technique [0002] Xinjiang is located in the northwest border of the motherland, with a fragile ecological environment and harsh natural environment. In the production process of protected areas in southern Xinjiang, there are problems such as serious soil salinization, low temperature stress in winter and spring, soil connection barriers, high cost of soilless culture substrates, low yield per unit area, and low utilization rate of water and fertilizer resources. In southern Xinjiang, there are more sunny days and less cloudy days, drought and less rain, long exposure time, more accumulated temperature, short frost period, large temperature difference between day and night, large desert area, serious land salinization, more than 14-16 hours of sunshine all day, and sunshine all year round. 2550-3500h. The solar radiation energy is very ric...
