CCTV News: Summer oil crops refer to oil crops harvested in summer. There is still about a week before the large-scale harvest of summer oil crops - winter rapeseed. This year, the area of ​​winter rapeseed in my country was 110 million mu, an increase of 7 consecutive years. At the same time, the climate is generally suitable and the growth is good, and summer oil crops are in sight.

Jiangxi is an important area for rapeseed cultivation in my country. At present, more than 9 million acres of rapeseed in the province have gradually entered the harvest of sickle. This year, Jiangxi has increased the cultivation of early-ripe rapeseed demonstration varieties. At the Thousand-Acre Rapeseed Demonstration Base in Suichuan County, the Institute of Oil and Materials of the Chinese Academy of Agricultural Sciences organized experts to conduct actual collection and production measurements on the early-mature rapeseed variety "Central Oil Early No. 1". The average yield per mu in the demonstration area reached 177.65 kilograms, breaking the record of rapeseed yield in my country under the "rice-rice-oil" three-ripe planting model.

"Rice-rice-oil" refers to the rotation of crops of early rice, late rice and rapeseed within a year. It is an important way for southern regions such as Jiangxi to use winter idle fields to increase the supply of oil crops. Therefore, the variety is the key to how to achieve the calm connection between rapeseed and rice on the basis of ensuring the double-season rice planting.

Du Dezhi, a job scientist at the National Rapeseed Industry Technology System: In the three-ripe areas, late rice is harvested in late October, and early rice is about to be planted around April 20, and it is only 180 days. Therefore, our short-term breeding varieties must meet the requirements of this time.

At present, the "rapeseed-rice" crop rotation model has been widely promoted in the southern regions. Anren County, Hunan Province is located in a hilly area with fragmented plots. By adapting early-mature rapeseed varieties with machine-harvesting technology, the utilization rate of winter idle fields has been increased to more than 90%.

Long Jun, a large grain grower in Anren County, Chenzhou City, Hunan Province: After the rapeseed is harvested, early rice can be planted. In the past, artificial can be planted up to 1 acre a day. Now with machinery, it can be planted 30 acres a day, which has nearly 30 times the efficiency. Rape straw can be returned to the fields and can also replace fertilizers. It is estimated that the yield per mu of early rice can increase by 2%.

According to the agricultural situation dispatch of the Ministry of Agriculture and Rural Affairs, the climate conditions of the main winter rapeseed production areas in my country were generally favorable last winter and this spring. In addition, the technical induction rate of production increase measures is high, rapeseed growth is the best in recent years, and a bumper harvest is in sight.
