Problems solved by technology

This traditional farming method will cause soil quality to decline, and soil and fertilizer loss will increase
Especially in winter and spring, the farmland has no vegetation cover and the surface is bare, which causes serious wind erosion of farmland soil.
Long-term traditional farming has made the land barren and crop yields low, seriously affecting farmers' income and sustainable development of the agricultural economy, and making the agricultural ecological environment increasingly fragile

Abstract

The invention discloses a cultivation method of protective tillage combined with the application of a rapid decomposing agent for stems, which comprises the following steps: (1) preparing an agent for rapid decomposing banana stems; The banana stalks left in the field are buried, and the banana stalks are sprayed with a rapid decomposing agent; (3) Dig planting holes and apply base fertilizer, and field management is carried out according to conservation tillage techniques; (4) Planting after the second year It is carried out on the center line of the two rows covered by the banana stems of the previous year, so that the next year's planting area is staggered from the previous year. The invention effectively solves the disadvantages of soil quality decline, serious loss of water, soil and fertilizer, frequent occurrence of soil-borne diseases and the like caused by traditional farming methods. The cultivation method can effectively improve the rhizosphere micro-ecological environment of banana plants for more than one cycle, promote the growth and development of bananas, reduce the use of chemical fertilizers and pesticides, not only reduce production costs, but also increase the land use efficiency of banana orchards.

Description

technical field [0001] The invention relates to a cultivation technique for crops, in particular to a cultivation technique in which protective tillage is combined with the application of a rapid decomposing agent for stalks. Background technique [0002] At present, as the main production area of ​​bananas in my country, Hainan Island has been plowing the soil with plows all year round, supplemented by rotary, harrowing, plowing and other topsoil cultivation measures. This traditional farming method will cause soil quality to decline and soil and fertilizer loss to increase. Especially in winter and spring, the farmland has no vegetation cover and the surface is bare, which has caused serious wind erosion of farmland soil. Long-term traditional farming has made the land barren and crop yields low, seriously affecting farmers' income and sustainable development of the agricultural economy, and making the agricultural ecological environment increasingly fragile. Therefore, ...
