Embodiment 1

[0026] The test material was the female parent of the broccoli variety "Tailu No. 1" bred by Taizhou Academy of Agricultural Sciences.

[0027] (1) Sowing seedlings

[0028] The sowing time of the female parent is early September, and the sowing time of the male parent is mid-September, and the seedlings are raised in the matrix plug. At the seedling stage, pay attention to the prevention and control of pests and diseases.

[0029] (2) Planting and field management

[0030] When the seedling age reaches 35 days, start to transplant, the male parent and the female parent are planted in alternate rows according to the ratio of 1:1, the row spacing is 50cm, the plant spacing is 50cm, and watering in time after completion of field planting.

[0031] Water and fertilizer management: Fertilize and water according to the common broccoli cultivation method;

[0032] Pest control: Spray corresponding drugs according to the possible occurrence and occurrence of pests and diseases;

...

Embodiment 2

[0043] With embodiment 1 (single stay side curd), comparative example 1 (single stay main curd) and the method described in comparative example 2 (retain side curd+main curd thinning branch) as 3 processes, each processing 3 repetitions. The experiment is carried out in 9 plots, each plot has one plot, with an area of ​​60m 2 , random block arrangement. One experiment was conducted in 2016-2017.

[0044] When the broccoli seed that method planting described in embodiment 1, comparative example 1~2 is ripe, each plot selects 10 strains and investigates every branch number, every strain pod number, every pod number and plot output, plot incidence situation (Only in 2017), measure the thousand-grain weight after threshing is completed.

[0045] result:

[0046] 1. Effects of pruning methods on seed yield and related traits

[0047] The results of variance analysis showed (see Table 1) that in the case of the same male and female parents, the pruning method had a significant ...

Abstract

The invention relates to the field of agricultural seed production and provides a method for increasing the yield of broccoli seed production. When the diameter of the main curd of the broccoli female parent reaches 3-5 cm, the main curd of the female parent is removed. The research of the present invention found that the pruning method can significantly affect the yield of broccoli seed production. The present invention improves the traditional pruning method during broccoli seed production. When the main curd grows to 3-5cm, the main curd is removed to promote side branches. Curd growth can increase the yield of broccoli seed production by 28% to 98%. The operation of the method of the invention is simple and convenient, and the maternal morbidity rate is reduced by more than 10%.

Description

technical field [0001] The invention relates to the field of agricultural seed production, in particular to a method for increasing the yield of broccoli seed production. Background technique [0002] The scientific name of broccoli is broccoli, which is native to the Mediterranean coast. Its edible part is rich in nutrition, and also contains glucosinolates, and its decomposition product sulforaphane is the plant active substance with the best anti-cancer effect found in vegetables, so it is also called "the king of vegetables" in western countries. In the mid-1980s, broccoli began to be introduced and tested on a large scale in China's coastal areas and big cities. In the late 1990s, it developed into a new high-quality and characteristic foreign exchange-earning vegetable in China. Zhejiang Province has always been the largest broccoli production base in China, among which only Taizhou City has a perennial planting area of ​​about 120,000 mu, accounting for three-fifths ...
