Abstract

The invention discloses a cultivation method for interplanting direct-seeding oilseed rape and double-cropping late rice. The cultivation method is characterized by including: selecting one of early and medium maturing varieties including Zhuliangyou 30, Zhuliangyou 819, Zhongzao 25, Zhongzao 35, Zhongjiazao 17 and Luliangyou 996 for early rice; selecting one of early maturing varieties including Wufengyou T025 and Wuyou 308 for late rice; selecting one of Ganyouza No.2, Ganyouza No.5, Fengyou 730, Fengyou 737, Dezayou No.5, Dezayou No.9 and Deyanyou No.19 for later-cropping oilseed rape; interplanting for 5-10 days. The cultivation method is simple in operation and remarkable in benefit, light and temperature resources can be fully used, cropping index can be increased, land consumption and land maintenance are combined to protect and increase soil fertility, common oilseed rape soil-borne diseases such as sclerotinia and the like can be controlled, conflicts of crop rotation arrangement of oilseed rape and rice can be effectively relieved, plant areas of oilseed rape can be directly added, and oilseed rape production capacity of main oilseed rape producing areas adopting a 'rice-rice-rape' triple cropping system can be improved remarkably.

Description

technical field [0001] The invention relates to crop cultivation, in particular to a cultivation method for two-season late rice and direct-seeding rape. Background technique [0002] A large number of slack rice fields have not been fully utilized, and only a small number of slack rice fields are planted with potatoes, pastures or vegetables. Planting rapeseed in the main rice-rice-oil three-ripening rapeseed production area is generally seedling cultivation and transplanting, which is an intensive cultivation method at the cost of labor-intensive, difficult to improve input-output efficiency, and is affected by the reduction of the number of rural labor force and the cropping of rapeseed and rice (Crops in Rotation System) arrangement has contradictory constraints, and there is no cultivation method suitable for large-scale promotion of second-crop late rice and direct-seeded rape. Contents of the invention [0003] The technical problem to be solved by the present inve...
