Cultivation method capable of increasing rape fruiting rate

Abstract

The invention discloses a cultivation method capable of increasing rape fruiting rate and belongs to the technical field of agriculture. The cultivation method includes following steps: step 1, applying boron fertilizer: dressing boron fertilizer while applying boron fertilizer as base fertilizer; step 2, selecting a selecting a place high in soil boron content, slightly acidic in soil, goodin soil texture, convenient for drainage and irrigation and away from industrial and mining enterprises, and not selecting alkaline and calcareous soil; step 3, performing field management includingproper early sowing, balanced fertilizing and reasonable irrigating; step 4, regulating plants: respectively applying paclobutrazol once at a seedling stage and a moss stage. By adopting the method, fruiting rate of specific rape can be increased effectively, yield and quality can be improved, farmers' income can be increased, and development of high-quality high-yield high-efficiency rape industry can be promoted.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a cultivation method for increasing the seed setting rate of rapeseed, in particular to a cultivation method for increasing the seed setting rate of "Changyouza No. 69" rapeseed. Background technique [0002] "Changyouza 69" rapeseed is a new three-line hybrid rapeseed variety bred by Hunan Xiangsui Seed Industry Co., Ltd. using the cytoplasmic male sterile line "3238A" as the female parent and "932R" as the male parent. In October 2015, it passed the approval of the Hubei Provincial Crop Variety Approval Committee, and the approval number was "Hubei Shenyou 2015007". The characteristic characteristics of this variety are introduced as follows: [0003] 1. Botanical features [0004] It is a semi-winter Brassica napus. The plant height is 168.8cm, it belongs to the middle branch type, and the branching is medium. The seedlings are upright, the leaves are green, the top leav...

AI Technical Summary

Problems solved by technology

When the soil available boron content is lower than 0.5mg / kg, rape is prone to flowering but not fruiting, and the seed setting rate is significantly reduced;

[0013] 2. The soil is alkaline

[0015] 3. No or insufficient application of boron fertilizer

[0016] There is no boron fertilizer or insufficient amount of boron fertilizer when applying base fertilizer, and no topdressing boron fertilizer is applied during the growth and development process, which is prone to flowering but not fruiting and low seed setting rate;

[0017] 4. Extensive cultivation management

If the soil is seriously waterlogged, the root system of rapeseed will be thin and weak, the ability to absorb boron will be poor, and the seed setting rate will be low due to boron deficiency;
