Embodiment 1

[0014] Step 1: First, establish a complete irrigation system to keep the groundwater depth below the critical depth. At the same time, establish a modern drainage system, mainly in the form of horizontal drainage and vertical drainage. Horizontal drainage is mainly in the form of open ditches and hidden pipes , can not only reduce the groundwater level, but also discharge the salt in the soil. The vertical shaft drainage is cheap, does not occupy land, has a large water volume, good water quality, flexible control and adjustment of the groundwater level, and less maintenance work. At the same time, it can be combined with irrigation. The plum-blossom-shaped well layout is the best for vertical wells, which can prevent the generation of self-toxic substances.

[0015] The second step: making microecological preparations, which is characterized in that it is prepared from the following raw materials in parts by weight: 4 parts of calcium sulfate, 6 parts of phosphogypsum, 5 parts...

Abstract

The invention discloses a continuous cropping obstacle auto-toxic substance improvement method. The novel continuous cropping obstacle auto-toxic substance improvement method provided by the invention has the following beneficial effects: the application of different organic fertilizers can significantly inhibit the toxic effect of auto-toxic substances on cucumber, improves the photosynthetic pigment content and the photosynthetic rate of the cucumber, and promotes the growth of the cucumber; the reason of the organic fertilizers capable of alleviating the toxic effect of cinnamic acid on the cucumber may be that the micro-ecological environment of rhizosphere is changed; a microecological preparation can promote growth, development and advanced flowering of crops, significantly improves the single-fruit weight , the fruit number per plant and the yield per plant of the crops, realizes the increase of the yield per plant and advanced maturity, and facilitates to the formation of the early-stage yield of the crops; exogenously added cane sugar can alleviate the phenomenon of inhibition on the length of radicle of the cucumber caused by a variety of auto-toxic substances, and protects cells from toxicity of the auto-toxic substances, wherein the detoxification mechanism of the exogenously added cane sugar is to glycosylate the auto-toxic substances through glycosyltransferase; meanwhile, a set of a self-carried irrigation and plant improvement system can provide a good growth environment for the crops.

Description

technical field [0001] The invention relates to the field of sewage treatment methods, in particular to a method for improving continuous cropping obstacle autotoxic substances. Background technique [0002] The autotoxic substances that caused cucumber continuous cropping obstacles were mainly p-hydroxybenzoic acid, ferulic acid, cinnamic acid, benzoic acid and so on. Autotoxic substances are one of the main causes of continuous cropping obstacles. They are ubiquitous in cucumber cultivation, and there are no economical and effective measures to completely avoid and eliminate them in agricultural production. Autotoxic substances have great effects on cucumber seed germination, cell division, and plant growth. These substances affect plant growth by affecting ion uptake, water uptake, photosynthesis, protein and DNA synthesis and many other pathways. [0003] However, there are relatively few researches on antidote reagents, detoxification mechanism and antidote applicatio...
