Red earth newly-cultivated orchard soil fertility rapid increasing method

Abstract

The invention provides a red earth newly-cultivated orchard soil fertility rapid increasing method. The method comprises the following steps of screening biological crusts, wherein according to southern soil climate characteristics and soil characteristics, and naturally developing biological crusts are selected; collecting biological crusts, wherein a 1-2 cm thick crust layer on the surface layers of the biological crusts is shoveled and smashed for use; preparing grout, wherein the smashed crust layer is mixed with matrix soil, nutrient solutions, bamboo fiber, adhesives and water to be uniform, and a grout is manufactured; spraying the grout, wherein the manufactured grout is evenly sprayed to the surface of soil of a newly-cultivated orchard, watering is performed, and the nutrient solution is applied; performing straw mulching, wherein two months later, the soil of the newly-cultivated orchard is covered with a layer of crop straw; performing sward coverage, wherein one year later, according to seasons, corresponding sward grass seeds are sown on the surface of the soil of the newly-cultivated orchard, and sward is cut at planted intervals so as to cover the surface of the soil. The problem that red earth region newly-cultivated orchards in southern China are poor in site condition and low in fertility level is solved.

Description

technical field [0001] The invention relates to the technical field of horticultural fruit tree cultivation, in particular to a method for quickly improving the soil fertility of newly reclaimed orchards in red soil. Background technique [0002] The fruit tree industry is a dominant industry in my country's agriculture and occupies a very important position in China's agricultural economy. The development of orchard industry has accelerated the development of red soil mountains. At present, the newly cultivated orchards in southern my country are mainly acidic red soil, the site conditions are poor, the soil is acidic and barren, the texture is hard, it is easy to form lumps, and the fertility level is low. These factors limit the early and high yield of fruit trees. Therefore, how to fertilize the soil, increase the organic matter content of the orchard soil, and improve soil fertility is one of the key technologies to ensure the steady development of new orchards in my c...
