Problems solved by technology

[0004] If organic vegetables do not use chemical fertilizers, pesticides, growth regulators and other substances in the planting process, in order to maintain soil fertility, only organic fertilizers, biological fertilizers and other fertilizers can be used. Therefore, it is easy to cause fertilizer nutrients to accumulate in the soil and cause secondary salinization of the soil.

Embodiment Construction

[0014] A method for alleviating secondary salinization of vegetable planting soil, such as figure 1 shown, including the following steps:

[0015] Step 1: After harvesting the vegetables of the previous season in mid-May, flood the vegetable greenhouse with water and close the greenhouse for 1-2 weeks. Through natural light heating, the effect of high temperature to reduce harmful bacteria is achieved, and preparations are made for planting saline-alkali-resistant rice;

[0016] Step 2: After the greenhouse is closed for 1-2 weeks, open the greenhouse and plant saline-alkali-tolerant rice. During this period, keep the relative humidity in the greenhouse at 50% to 90%; Above ℃, the suitable temperature for panicle differentiation is about 30℃, the suitable temperature for heading is 25℃~35℃; the optimum temperature for flowering is about 30℃, and after 3 months of growth of saline-alkali-tolerant rice, regardless of whether the rice is mature or not, the rice should be cut off ...

Abstract

The invention discloses a method for relieving soil secondary salinization of a vegetable planting field. Residual salt in the planting field can be well absorbed by intercropping first-stage saline-alkaline tolerant hybrid rice in the organic vegetable planting field according to the characteristic that saline-alkaline tolerant rice can well adapt to soil with high salt content and has high salt adsorption capacity, the effect of relieving soil secondary salinization is achieved, after the saline-alkali tolerant rice is mature, straw of the saline-alkali tolerant rice is cut up and applied to organic vegetable planting field soil as an organic slow-release fertilizer, soil nutrient balance is well kept, and the yield of vegetables is increased.

Description

technical field [0001] The invention relates to the field of ecological restoration, in particular to a method for alleviating secondary salinization of vegetable planting soil. Background technique [0002] In recent years, with the rapid development of my country's facility agriculture, the planting scale of facility organic vegetable greenhouses has continued to expand. Large-scale protected cultivation and long-term repeated use have resulted in many soil problems, such as soil compaction, soil secondary salinization, soil nutrient imbalance, and soil acidification, among which the problem of soil secondary salinization is particularly prominent. [0003] The secondary salinization of soil is mainly due to unreasonable fertilization, improper irrigation methods, rising groundwater level and increased salinity, which lead to a large accumulation of nutrient salt ions (mainly NO3-, SO4-) on the soil surface, making the soil The increase in salt content has caused problems...
