Embodiment Construction

[0019] The present invention will be further described below, and the protection scope of the present invention is not limited to the following description.

[0020] A method for live broadcasting of rapeseed, comprising the following steps:

[0021] A. Seed selection: select rapeseed varieties with short growth period, short plant height, low branch position, and high uniformity, remove empty, mildewed, insect-eaten, and damaged seeds, and choose large-grained, mildew-free and insect-free seeds sow seeds

[0022] B. Land selection: Select the concentrated plots that are convenient for the harvester to use as the land for planting rapeseed;

[0023] C. Soil preparation: before sowing, spray herbicides in the field to remove weeds in the field;

[0024] D. Sowing: Sowing in late September, evenly sowing 2.5kg of seeds per acre, mixing 2.5kg of seeds with 4kg of small particle urea before sowing, and applying 2kg of borax per acre after sowing, to prevent boron deficiency ...

Abstract

The invention discloses a method for direct seeding of rape, which includes seed selection, land selection, land preparation, seeding, pre-emergence weeding, topdressing, ripening acceleration and mechanical harvesting. The method used for planting rape has the advantages that heights of ripe rape plants can be maintained substantially equal by means of seed selection and ripening acceleration, and the ripe rape plants are suitable for mechanical harvesting and high in efficiency; the ripening cycle of rape is short and between 25th April and 30th April when seeding begins in late September, whereas the ripening cycle of the rape planted by traditional transplanting methods is between 8th May and 15th May; straws of the rape planted by direct seeding are thin and can be directly and automatically broken and crushed by a harvester in harvesting so as to facilitate turning and covering, water and fertilizer conservation of soil are improved, and environmental impacts by straw incineration are avoided.

Description

technical field [0001] The invention relates to plant planting technology, in particular to a method for live-seeding rapeseed. Background technique [0002] Because rice planting has very strict requirements on the sowing time, in order to provide a good stubble for rice planting, facilitate the arrangement of rice planting, promote early growth and rapid development, ensure safe encounters at the flowering period, and promote stable production, so when the previous rapeseed is sown, the direct seeding method is usually selected conduct. Generally, direct seeding fields can be harvested 10 days earlier than transplanting fields, providing sufficient time for rice planting. The live broadcast also omits the seedling raising process, saving a lot of labor and time. However, there is a problem of low uniformity in rapeseed planted by live broadcasting. The height of mature rapeseed is uneven, and it becomes very difficult to harvest and threshing with harvesters, and manual ...
