Sugarcane rotation cultivation method of three harvests within two years

Abstract

The invention discloses a sugarcane rotation cultivation method of three harvests within two years. The method comprises the steps of planting short-term crops such as soybean, corn, watermelon and the like in a sugarcane field in spring of the first year, transplanting sugarcane seedlings after the soybean, corn, watermelon and the like are harvested, harvesting sugarcane seeds and keeping perennial roots in February and March of the following year, and harvesting perennial root raw material sugarcane in December of the second year. By adopting the method, it is possible to harvest crops suchas the soybean, corn, watermelon and the like one time in two years in the sugarcane field and harvest the sugarcane twice, which not only utilizes lands reasonably, but also alleviates the obstacleof continuous sugarcane cropping, the combination of land use and land maintaining is achieved, the speed of sugarcane breeding is improved, and the upgrading of varieties is accelerated.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a sugarcane crop rotation cultivation method for two years and three harvests. Background technique [0002] Our country has a lot of people and little land, and land resources are in short supply. Over the years, we have fed more than one billion people with limited arable land, but we have also paid a huge price. For a long time, China's intensive agricultural development model of "high multiple cropping, high input, and high output" has used a large amount of chemical fertilizers in excess , pesticides, soil improvers, plant growth regulators, feed additives and other chemical products not only greatly increase the cost of agricultural production, but also greatly pollute the ecological environment of farmland. Factors of sustainable agricultural development. [0003] After continuous cropping of the same crop or related crops, even under normal management conditio...

Problems solved by technology

However, sugarcane breeding has problems such as unscientific breeding varieties, unreasonable breeding time, and lack of breeding technology.

In Guangxi, there are still many problems such as large population and small land, limited cultivated land, low level of sugarcane planting scale, serious lack of mechanization, weak sugarcane field infrastructure, and very serious single varieties; sugarcane is planted for many years. For more than 30 years, no reasonable crop rotation has been achieved, 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, and the output rate per unit area of ​​land has declined, which has seriously restricted the development of my country's sugar industry.
