A method for crop rotation and intercropping of sugarcane, silage corn and millet

Abstract

The invention discloses a method for crop rotation and intercropping of sugarcane, silage corn and millet. The method is to intercropping sugarcane and millet or silage corn on a piece of land, and the perennial root sugarcane is grown every 3-5 years. Renovate the land, rotate millet or silage corn in the area where sugarcane was originally planted, and sugarcane in the area where millet or silage corn was originally planted. Due to the short growth cycle of millet and silage corn, it is basically possible to plant one crop of millet and one crop of silage corn every time sugarcane is planted, that is, to achieve one crop of sugarcane, one crop of millet and one crop of silage corn every year. Therefore, the method of the present invention combines the two planting modes of crop rotation and intercropping, so that the land is rotated, avoiding continuous cropping obstacles, and at the same time makes full use of the land, improves land output, reduces land costs, and realizes The harvest of the three crops of sugar cane, silage corn and millet has been guaranteed.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for crop rotation and intercropping of sugarcane, silage corn and millet. Background technique [0002] sugar cane( Saccharum officinarum ) is one of the important economic crops in my country, and is the main sugar crop in my country. The sucrose production accounts for more than 90% of the total sugar production in the country. Guangxi is the largest sugarcane and sugar production base in my country. The annual sugarcane planting area is about 11.5 million mu, accounting for about 60% of the national sugarcane planting area, and the sugarcane sugar production accounts for more than 65% of the country. However, in recent years, domestic sugar prices have continued to fall, and due to the impact of rising costs of land and labor, the cost of sugar production in China has remained high, and the sugar cane sugar industry has suffered huge losses. Coupled with the l...

However, in recent years, domestic sugar prices have continued to fall, and due to the impact of rising land and labor costs, the cost of sugar production in China has remained high, and the cane sugar industry has suffered huge losses

Coupled with the long-term continuous cropping of sugarcane, most of the sugarcane areas have been continuously cropped for more than 30 years without a reasonable crop rotation. The physical and chemical properties of the land have changed, and the pests and diseases have aggravated, which has affected the growth and development of sugarcane. The output rate per unit area of ​​land decline, seriously restricting the development of my country's sugar industry
