Novel protected cultivation soil hardening improvement technology

Abstract

The invention discloses a novel protected cultivation soil hardening improvement technology. The novel protected cultivation soil hardening improvement technology comprises the following steps: takinga soil sample for test after uprooting of vegetables subjected to protected cultivation after edible portions of the vegetables are harvested, and performing test and assay on nitrogen, phosphorus, potassium, salt and organic matter contents, as well as pH value, of the soil sample; waiting for 3-5 days after the sampling and the assaying, carrying out treatment by using a soil disinfector alongwith watering on ridged field for cultivation use; waiting for one week after the treatment by using the soil disinfector, uniformly spreading 2 tons of a humic acid-enzyme bacterium organic fertilizer and 200 kilograms of biomass carbon onto per mu of the ridged field for the cultivation use; determining dosage of a soil conditioner on basis of soil test and assay data; carrying out rotary tillage, namely carrying out rotary tillage at a depth of 30 cm or above by adopting high-ridge field preparation; carrying out timely field planting with paenibacillus polymyxa applied in holes, preparinga homemade microbial enzyme fermentation broth by using zymogen strains, and applying 50 kilograms of the microbial enzyme fermentation broth and 1 kilogram of mineral-source humic acid along with water onto per mu of the ridged field for the cultivation use by carrying out rinsing; and then, waiting after one month of growth of crops, fermenting residual branches and imperfect fruits of the cropsby using zymogen strains so as to prepare a homemade enzyme fermentation broth, and applying 50 kilograms of the enzyme fermentation broth and 1 kilogram of mineral-source humic acid along with wateronto per mu of the ridged field for the cultivation use by carrying out rinsing.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a new technology for improving soil compaction in protected cultivation. Background technique [0002] The long-term large-scale input of agrochemicals is an important reason for the sustained and stable growth of intensive vegetable production in China in recent years. However, the excessive application of chemical fertilizers and pesticides, coupled with unreasonable water and fertilizer management methods, has destroyed the soil structure and increased soil bulk density. , The porosity is reduced, the soil is compacted, and then affects the soil's arableness, and finally leads to the obstacle of vegetable joints, which seriously restricts the safe and sustainable development of facility vegetable production. [0003] The disclosure of the above background technical content is only used to assist in understanding the inventive concepts and technical solutions of the pr...
