Method for constructing medium-low yield field soil plough layer structure of Xinjiang muskmelons

Abstract

The invention aims to provide a method for constructing a medium-low yield field soil plough layer structure of Xinjiang muskmelons. According to the method, previous straw crops are crushed and returned to the field, mechanically deep plowing, deep scarifying and flooding irrigation in winter are carried out, a base fertilizer is applied in the next year, irrigation with sufficient water is ensured before sowing, and disease-resistant, high-quality and high-yield varieties are selected; a soil conditioner or a mineral source potassium fulvate fertilizer is applied along with water in a melon seedling stage and a flower bud stage, so that the soil nutrient content is gradually increased, the physical and chemical properties of soil are improved, the soil bulk density is reduced, and a good soil plough layer structure of a medium-low yield field of the muskmelons is constructed. The combination of land utilization and recuperation is further promoted, the formation of a medium-low yield field soil aggregate structure of the muskmelons is promoted, soft plough layer texture, good drainage and air permeability, strong water and fertilizer holding ability, good soil plowing suitability, light hardening degree and low disease, pest and weed occurrence rate are realized, and the seeding emergence rate and strong seedling rate of the muskmelons can be increased; and meanwhile, adverse effects of continuous cropping obstacles are reduced, then the reasonable plough layer soil requirements for yield increase and stable yield are met, and finally, the aim of continuous high yield and high quality of the muskmelons is achieved.

Description

technical field [0001] The invention relates to the technical field of crop planting, and more specifically relates to a method for constructing soil plow layer structure in low-yield muskmelon fields in Xinjiang. Background technique [0002] In recent years, due to the impact of scattered land management and long-term use of small power tools, the area of ​​large-scale mechanized deep plowing and subsoiling operations has become less and less, resulting in shallower soil effective cultivation layers, and mechanical compaction has reduced the soil surface bulk density. increase, resulting in soil compaction, thickening of the bottom of the plow, weakening of fertilizer and water supply capacity, and serious soil moisture loss, resulting in a continuous decline in soil fertility, limiting the growth and development of crop roots, and adversely affecting the yield and commerciality of melons. Xinjiang's natural ecological environment is relatively harsh, so the cultivation ti...

Problems solved by technology

[0005]Aiming at the long-term existence of heavy soil compaction, imbalance of soil microbial flora, large number of harmful pathogenic microorganisms, frequent occurrence of diseases and insect pests, and soil-borne The disease is getting worse year by year, the incidence rate of melon field plants is high, the content of soil organic matter is low, and the physical and chemical properties of the soil plow layer are poor, resulting in technical problems such as poor reproducibility of high-yield melons. The plowing layer structure method, this method is to crush the previous straw crops and return them to the field, after deep plowing and deep loosening, winter irrigation with a large amount of water, and use decomposed farmyard manure, oil residue, microbial fertilizer and nitrogen, phosphorus, and potassium fertilizers as base fertilizers in the next year Apply, ensure sufficient water for irrigation before sowing, select suitable varieties, combine with water at the seedling stage and flower bud stage of melons and apply soil amendments or mineral source fulvic acid potassium fertilizers, and use the light and simplified field management methods of melons in the open field to complete the steps
