Problems solved by technology

The main problems of this traditional cultivation mode are: 1. The land is idle for up to four months throughout the year, and the land utilization rate is low; 2. The soil is soaked in water for a long time, and the soil structure cannot be effectively improved; 3. No green manure is planted, coupled with less application of organic fertilizers and a large amount of chemical fertilizers, resulting in the loss of soil nutrients, increasing the rate of land barrenness and causing soil compaction; Effective survival, soil-borne diseases and insect pests are serious, causing the disease and insect pests to be rampant again in the second year

Abstract

The invention discloses a crop rotation method for southern rice areas. In a cycle of two years, summer dryland commercial crops, winter dryland cereal crops, rice and winter green manure crops are rotationally planted; rotation of paddy field crops and dryland crops is adopted; soil structure is improved, and less disease and insect damage occurs; crops for rotation are reasonably arranged; the winter crops are planted, and land utilization rate is increased; the green manure crops are planted, farming and land maintaining are combined, and soil fertility is improved; the commercial crop planting and cereal crop planting are combined, and economic benefit is increased.

Description

Technical field [0001] The invention relates to a crop planting method, in particular to a crop rotation planting method in southern rice regions. Background technique [0002] At present, the southern rice area generally adopts early rice, late rice and a two-season cultivation mode in winter, and the planting time is from March to November. The main problems of this traditional cultivation mode are: 1. The land has been idle for up to four months throughout the year, and the land utilization rate is low; 2. The soil has been soaked in water for a long time, and the soil structure cannot be effectively improved; 3. No green manure is planted, combined with a small amount of organic fertilizer, and a large amount of chemical fertilizers are used, resulting in the loss of soil nutrient elements, and the increasing speed of soil infertility, which makes the soil easy to compact; 4. Continuous cropping of rice for many years can easily cause rice pathogenic microorganisms and pests ...
