Abstract

The invention relates to the field of crop planting, and discloses an oilseed rape seedling-raising transplanting method. The method includes: selection of rape seeds, once mechanical sowing seedling-raising, management of seedling beds, and field transplanting; the once mechanical sowing seedling-raising includes using a seedling bed sowing machine having a sowing assembly, a rotary tillage assembly and a disc plough to complete turning over, ditching, fertilizing, sowing and soil covering once. The area ratio of the seedling beds and the field is 1:9-10; a base fertilizer is a compound fertilizer, and the use amount of the base fertilizer is 450-525 Kg / hm<2>; the compound fertilizer includes at least 15 wt% of nitrogen elements, phosphorus elements, and potassium elements respectively. According to the method, the oilseed rape planting method can be simplified, and the labor intensity of artificial planting can be relieved; an improved seedling bed sowing machine is used to perform sowing, the seedling emergency is neat and even, high seedlings and weak seedlings can be reduced, the quality of young seedlings of the oilseed rape is ensured, and the sowing amount can be adjusted; and the method can be used for direct-sowing production of the oilseed rape and can reduce input cost.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a method for growing and transplanting rape seedlings. Background technique [0002] Rapeseed is an important oil crop in the world, and it is also a source of protein, feed, energy, nectar and land crop, with high comprehensive utilization value. Among the world's rapeseed planting area and total output, China's rapeseed planting area ranks second, and its total output ranks third. [0003] At present, my country's rapeseed planting methods mainly include direct seeding and seedling transplanting. Among them, the seedling raising and transplanting method has obvious advantages: 1) It can significantly increase crop yield; 2) It can solve the contradiction between multi-crop crops and increase the multiple cropping index; 3 ) The root system of the crops is deeply distributed and the stalks are thick, and the lodging resistance is strong; 4) It can effectively avoid natural disasters...
