Rape three-refined plantation method

Abstract

The invention discloses a rape three-refined plantation method comprising the following steps: S1, finely culturing and strong seedling, selecting a proper seedbed and applying a base fertilizer, sowing 0.5kg / mu on the seedbed, fully germinating and final singling, leaving 100-120 plants in every square meter, and controlling the seedling age at 25-30 days; S2, finely planting and increasing density, transplanting rape strong seedlings to a big field, re-applying base fertilizer in transplanting, mixing the base fertilizer and applying same into a pond or a trench, and controlling the planting density at 8000-8500 plants / mu; S3, refined management, irrigating the rapes in the day when the strong rape seedlings are transplanted, pouring water for many times after transplantation, spraying insecticide, applying fertilizers, wherein the water is fast irrigated and drained, the fertilizers mainly comprise nitrogen, phosphor, potassium and boron fertilizers, and the nitrogen fertilizer application is strictly controlled. The three-refined technology can realize scientific plantation in seedling, transplanting and management levels, thus ensuring each node of the rape production, effectively ensuring rape yield increase, ensuring rape quality, and realizing high yield.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a three-fine planting method for rapeseed. Background technique [0002] Rapeseed is one of the main oil crops. It has a long history of planting and occupies an important position in agricultural production. The domestic demand for vegetable oil is growing rapidly and the market space is large. According to the comprehensive analysis of population increase, economic development and the growth rate of vegetable oil consumption in recent years, the future During the period, my country's vegetable oil consumption will continue to maintain a relatively high growth rate. [0003] The planting area of ​​rapeseed is relatively concentrated. Under the current situation that the rapeseed planted is large in scale, good in foundation, good in market and welcomed by the masses, the main problems found are: single variety, not prominent dominant varieties; large seeding vol...

AI Technical Summary

Problems solved by technology

[0003] Rapeseed is relatively concentrated in its planting area. Under the current situation that the rapeseed planted has a large scale, a good foundation, a good market and is welcomed by the masses, the main problems found are: single variety, not prominent dominant varieties; large seeding volume, low seedling quality; The density is not enough, the total yield per mu is low; the fertilization is unscientific, which increases the production cost; the quality of the labor force is not high, which restricts the increase of production and value; the input is insufficient, and the production is unstable

Therefore, there are unfavorable factors in the sowing, transplanting and management of rape planting, resulting in low yield and low production efficiency.
