Ecological cultivation method for broadcast sowing intercropping of konjak and selfheal to prevent and control weeds

Abstract

The invention belongs to the field of field intercropping methods, and particularly relates to an ecological cultivation method for broadcast sowing intercropping of konjak and selfheal to prevent and control weeds. The method comprises the steps that furrow opening planting is carried out according to 100-150 cm in a stretching mode, the furrow width ranges from 30 cm to 50 cm, the furrow face width ranges from 100 cm to 120 cm, the furrow height ranges from 20 cm to 50 cm, the furrow faces are prepared, operation is carried out on the furrow faces, strip furrow transplanting is carried out, 2-5 rows are planted on each furrow face, the row spacing ranges from 20 cm to 50 cm, selfheal and konjak are intercropped, the plant spacing ranges from 10 cm to 30 cm, one konjak plant is planted every 2-5 plants, and the konjak plant spacing ranges from 20 cm to 50 cm. The intercropping method can protect the growth environment of a konjak planting field, reduce soil pollution, improve the output value per mu and increase benefits; and the profit can be increased by 7.3% compared with that of pure konjak.

Description

technical field [0001] The invention belongs to the technical field of field intercropping, and in particular relates to an ecological cultivation method for sowing and intercropping konjac and Prunella vulgaris to prevent and control weeds. Background technique [0002] Intercropping refers to the method of planting two or more crops alternately in rows or in strips during the same growth period on the same field. Intercropping can improve land use efficiency, and the crop complex group formed by intercropping can increase the interception and absorption of sunlight and reduce the waste of light energy; the intercropping of two crops can also produce complementary effects, which have a slight effect on plant types with different heights and growth periods. Reasonable collocation of uneven crops and the arrangement of wide and narrow planting row spacing in the field will help to improve the effect of intercropping. [0003] Konjac, also known as konjac and pedicel lotus, i...
