Embodiment Construction

[0016] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the invention.

[0017] see figure 1 , the present invention provides a method for improving soil fertility in saline-alkali land by planting quince, comprising: deep plowing and irrigation for salt isolation S1: from March to June every year, select saline soil with a soil salt content of 0.3% or an alkaline land with a pH value of 9.5 Dig the soil, clear the weeds in the saline-alkali land, and form a dense and compacted soil layer at least 40cm below the surface, so as to avoid the upward movement of the groundwater with high salt content, and avoid damage to the planted vinaigrette or other plants....

Abstract

The invention is suitable for the technical field of saline-alkali soil improvement, and provides a method for improving the soil fertility of saline-alkali soil by planting sesbania. The method is characterized by comprising the steps of deep ploughing, irrigation and salt separation, wherein soil turning is carried out, weeds of the saline-alkali soil are removed, a compact soil layer is formedbelow the earth surface, and underground water high in salt content is prevented from moving upwards; sowing and fertilizing, wherein seeds need to be soaked or sand is added for wiping the seeds before sesbania sowing, a single sowing mode is used, phosphorus fertilizer is applied, the yield of sesbania is increased, and the content of nitrogen and phosphorus in sesbania is increased; harvestingand fertilizer retention, wherein after the sesbania is ripe, direct ploughing is conducted, straw and livestock manure can be heaped and applied to serve as base fertilizer or conduct topdressing, stalks need to be cut off, chopped and completely buried in the soil layer to prevent moisture evaporation, after sesbania is turned, the total quantity of water-stable aggregates of soil is increased,the soil volume weight is reduced, the porosity is improved, and the soil can be prevented against salt return. Therefore, the fertility of the saline-alkali soil can be improved, and conditions of the saline-alkali soil for planting crops are improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement in saline-alkali land, in particular to a method for improving soil fertility in saline-alkali land by planting quince. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. The fundamental reason for the formation of saline-alkali soil is poor moisture status, so in the early stage of improvement, the focus should be on improving the soil moisture statu...
