Rapeseed three-dimensional dense stem planting method

Abstract

The invention discloses a rapeseed three-dimensional dense stem planting method and belongs to the technical field of crop planting. The technical problem to be solved is to provide the rapeseed three-dimensional dense stem planting method to ensure that multiple thick and strong branches capable of normally setting seeds are branched out of one plant to improve the density of fruit bearing branches, thereby improving the acre yield of rapeseeds. An adopted technical scheme is that the rapeseed three-dimensional dense stem planting method comprises the following steps that: an existing sowing and transplanting method for planting the rapeseeds is adopted, and when sowing is performed according to the existing cultivation method of the rapeseeds, the row pitch for rapeseed seeding is 70-80 cm, and the plant spacing of the plants of each row is 15-25 cm; in the early jointing growth period of the rapeseeds and when each rapeseed has 5-6 nodes, positive apexes are removed to ensure that each plant is branched into 5-6 thick and strong branches in growth; and when each branch of each rapeseed plant grows to be of 9 leaf ages, 12 leaf ages or 15 leaf ages, the apexes of each branch are removed to promote fruition of the branches. The planting method disclosed by the invention is mainly used for improving the yield of the rapeseeds.

Description

technical field [0001] The invention relates to a method for planting three-dimensional dense stems of rapeseed, which belongs to the technical field of crop planting, and in particular relates to a method for increasing the yield of rapeseed. Background technique [0002] Because the growth of rapeseed needs enough space, when planting rapeseed, it needs a large space to allow the plants to grow. The conventional row spacing of rapeseed planting is 40cm and there is only one main stem. Although there are normally growing branches, the branches are weak and difficult to grow. Normal seeding can basically negligibly contribute to the yield. Although the quality of the main rapeseed is guaranteed, it is difficult to increase the yield. Most of the existing cultivation methods are to increase the yield of rapeseed from the idea of ​​improving rapeseed, but the effect of increasing yield is still very small. Up to now, the yield per mu of rapeseed in the world is 300kg, which i...
