Is it good to plant rapeseed this fall? After a rigorous variety comparison test, at the same time organize relevant experts to observe the comments on the spot, recommend the following varieties to the majority of farmers:
Zhongyouza 12: The Institute of Oil Crops of the Chinese Academy of Agricultural Sciences has developed high-yield and high-yield varieties of late-maturing crops. The main features are strong growth, low branching sites, many knots, strong resistance to lodging, high yield, and yields close to 250 kg per mu. A large area of ​​the main push variety increased production by nearly 20%, the quality meets the double low quality rapeseed standard. As the variety matures late, it is best to plant in the low mountain Pingba area. During production, it is necessary to pay attention to proper early sowing, reasonable close planting, increase of base fertilizer, formula fertilization, and supplementation of boron fertilizer.
Hope 98: The Oil Crop Research Institute of the Chinese Academy of Agricultural Sciences has developed a medium-yield high-yield and high-quality variety, formerly known as Zhongyouza No.11. The main features are high output and high oil content. The test yield is about 240 kg per mu, which is 15% higher than the current large-scale main push varieties. The oil content is up to 45%, and the quality meets the double low quality rapeseed standard. The variety has a moderate growth period, strong disease resistance and lodging resistance, and wide adaptability. It is suitable for planting in various mouthwashes and various altitudes. Because the variety is lightly susceptible to sclerotium disease, it is recommended to pay attention to the flowering period to prevent the occurrence of sclerotinia.
Zhongnongyou 2008: Huazhong Agricultural University bred high-yield and high-quality rapeseed. The main features are strong seedling stage, compact plant type, branching, multi-grain, moderate growth period, strong antiviral disease resistance and lodging resistance, good comprehensive traits, high yield, test yield per mu 230 kilograms, an increase of 14% over the current large-scale main varieties. The variety has wide adaptability, and can be planted in paddy fields or dry land, and should be properly planted. Due to mild sclerotium disease, attention should be paid to the prevention and treatment of sclerotinia.
CNPC 98D: The Oil Crop Research Institute of the Chinese Academy of Agricultural Sciences has developed high-yield, high-quality, medium-ripe and multi-resistant varieties. The main features are particularly strong seedling growth, strong stems, strong lodging resistance, high antiviral disease, moderate growth period, high yield, and the yield per mu is close to 130 kg, which is more than 10% higher than the current large area. Because the variety is thick and strong, it is especially suitable for "one vegetable and two use" cultivation.
In addition, although the production of Huyouza No. 1 and Fengyou 701 is not particularly prominent, it has strong resistance to stress, good stability and good sclerotinia disease. It is suitable for direct cultivation in dry land and increases yield and efficiency by increasing planting density.
All of the above varieties are double-low-quality rapeseed, which is sensitive to boron deficiency. Therefore, it is necessary to add boron fertilizer to the base fertilizer, and at the same time, it can be combined with flower-preventing disease prevention (mainly sclerotinia) to spray quick-acting boron fertilizer.
In addition, when purchasing the above rapeseed seeds, the majority of farmers must purchase them at a fully licensed store and ask for proof of purchase when purchasing seeds. Never buy the seeds of a mobile trader to prevent the purchased seeds from being "pseudo-species" or "inferior seeds", although they are excellent varieties, and lay a good foundation for the need to safeguard rights in case of problems after planting.
