Embodiment 1

[0041] From 2014 to 2015, it was planted in Gaoqian Village, Dongqianhu Town, Yinzhou District, Ningbo City to Lijiayang Village, Wuxiang Town, between 121°08'~121°54' east diameter and 29°37'~29°57' north latitude According to the point layout test, the annual average temperature is 16.2°C, the annual average sunshine time is 2070 hours, and the annual average precipitation is 1538.8 mm.

[0042] (1) Selection of seed production bases and fields:

[0043] Planting fields should be selected with fertile soil, convenient drainage and irrigation, no cruciferous crops have been planted within 3 years, and there are no mustard vegetables more than 1 km around. The stem mustard cultivation field is generally 45 meters long, divided into 4 furrows, and the furrow width (connecting ditch) is 1.5 meters. The purpose of this design is to set up the net cover.

[0044] (2) Variety selection

[0045] The hybrid variety 'Yongza 5' was selected.

[0046] (3) Sowing date and seeding rate ...

Abstract

The invention relates to a method of assisting pollination of hybrid brassica juncea var. tumida Tsen et. Lee by utilizing houseflies. The method includes (1) selecting a base and a field, (2) selecting a variety, (3) sowing, (4) performing field planting, (5) breeding the houseflies, (6) building a gauze shed, (7) allowing the houseflies to perform pollination, (8) killing the houseflies, (9) performing field management and (10) harvesting seeds. The method has advantages of simple operation, a high pollination speed, and uniform, centralized and accurate pollination, saves the manual cost, overcomes problems of poor pollination effects, a low hybrid seed yield, and the like, and provides a pollination technique which is high in pollination efficiency, simple and feasible for better application in production.

Description

technical field [0001] The invention belongs to the technical field of plant pollination at flowering stage, and relates to a method for using houseflies to assist the pollination of hybrid stem mustard. Background technique [0002] Stem mustard, commonly known as mustard mustard, belongs to Brassica mustard species of Brassicaceae and is a kind of mustard for stems. Its product organs can not only be sold fresh, but also can be processed. The processed products of stem tubers are not only sold well in China, but also enjoy a high reputation overseas. Mustard mustard is mainly processed and sold, which can greatly increase its added value and increase farmers' income. Zhejiang Province is a traditional production area of ​​mustard mustard, with a stable cultivation area of ​​about 350,000 mu. The differentiation of flower buds of stem tuber mustard generally does not require strict low-temperature vernalization, and the requirements for the length of sunshine are not very...
