Rice ridge-pulverization ecological and efficient cultivation method

Abstract

The invention discloses a rice ridge-pulverization ecological and efficient cultivation method. The rice ridge-pulverization ecological and efficient cultivation method comprises the steps that an auger-bit machine enters soil and vertically rotates, wherein the machine enters the soil to the depth of 25-30 cm; ridge-pulverization soil drilling and fertilization are carried out at the same time, and the land is not harrowed so that bottom deep-layer soil will not be disturbed afterwards; meanwhile, ridge-pulverization deep rotary tillage does not need to be conducted again when second rice crop is planted, no tillage or only 3-4 cm shallow tillage is needed, stratification and air permeability of the bottom soil are kept, and field farm operation such as cultivation, weed control, fertilization, pesticide application and water management is conducted in a cooperative mode. The rice ridge-pulverization ecological and efficient cultivation method can effectively solve the problem that a traditional farming mode easily causes soil environmental degradation, effectively improve labor efficiency of ridge-pulverization cultivation, achieve the effect that deep ploughing is not needed within 3-4 years each time ridge-pulverization is conducted, and keep the stable yield and the yield increase of rice continuously, thereby having important value and significance in the field of rice cultivation.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to an ecologically efficient cultivation method for rice powder ridges. Background technique [0002] As we all know, rice has a variety of cultivation methods, such as hydroponics, dry cultivation and direct seeding. Among them, the rice planting method that has been inherited for a long time in history and is still widely used in a large number is water-borne. Complex management links such as insect pest prevention and control require a lot of manpower, material resources and financial resources. This conventional rice cultivation mode also requires timely and necessary water and fertilizer management. For example, when rice is transplanted, it is necessary to apply sufficient base fertilizer. Fertilizer, panicle fertilizer, etc., and water management should be rationally arranged and adjusted in conjunction with the entire growth period of rice; and this traditional rice planti...

Among them, the rice planting method that has been inherited for a long time in history and is still widely used in a large number is water-borne. Complex management links such as insect pest prevention and control require a lot of manpower, material resources and financial resources

This conventional rice cultivation mode also requires timely and necessary water and fertilizer management. For example, when rice is transplanted, it is necessary to apply sufficient base fertilizer. Fertilizer, panicle fertilizer, etc., and water management should be rationally arranged and adjusted in conjunction with the entire growth period of rice; and this traditional rice planting model has little potential to increase yield per unit area, because: 1. The paddy field cultivation layer is shallow , generally about 13cm, the amount of soil loosening and original nutrients in the paddy field is seriously insufficient, which cannot meet the needs of hybrid rice and other improved varieties of soil environment

2. The paddy field base fertilizer is applied before the whole field or when the tractor is rotary plowing the field, and a large amount of water in the paddy field will cause the mud and fertilizer to flow out. In addition, the serial irrigation and flood irrigation before and after transplanting will cause serious loss of water, soil, and fertilizer. It not only reduces the soil fertility of paddy fields, but also easily causes pollution and affects environmental protection

3. Paddy paddy cultivation, the soil is easy to stick and compact, the soil volume is large, the soil oxygen content is low, and the activities of aerobic microorganisms in the soil are hindered, which seriously affects the development and growth of the rice root system, which in turn affects the plant height and photosynthetic efficiency.

4. Waste of labor, water, fertilizer and medicine

Years of repeated cropping in paddy fields has led to serious pests and diseases, while the paddy fields are still dominated by chemical fertilizers, which has seriously deteriorated the soil environment, and the deterioration of the planting environment in paddy fields has directly increased the cost of planting and production

5. Traditional rice cultivation is under flooding conditions for a long time, coupled with soil compaction, it is easy to produce greenhouse gases such as methane, which affects the ecology

[0004] Although the above Fenlong cultivation techniques can change the defects in the existing rice cultivation techniques, from the perspective of resource utilization, artificial input and rice output rate, after Fenlong cultivation, before rice transplanting, the soil after Fenlong will be used. If the disturbance is leveled by manual or mechanical rakes, the good layered structure and air permeability of the powder ridge soil have been destroyed. When the next season of rice is planted, the powder ridge needs to be plowed again, which increases production input costs and reduces labor efficiency.
