Embodiment Construction

[0013] 1. Seed and substrate selection

[0014] In this experiment, the parents of Shenglu were used, and the substrate was specially selected for the Swiss "Pinshi" vegetable substrate.

[0015] 2. Sowing

[0016] On August 25 (Jurong, Jiangsu), the seedlings were grown in plugs and managed after emergence.

[0017] 3. Transfer and cut the ball

[0018] Plant the field when the seedlings have 4 leaves and one heart (September 25 to October 5), the row spacing is 45*40cm, and the plants are divided into 3 plots, and each plot is planted with 200 plants (100 plants for each parent).

[0019] Around January 14th, cut off all the florets and main stems 15cm below the florets from all plants in a plot (Plot 1).

[0020] In a plot at the beginning of March, cut off the main flower bulb and the main stem 15cm below the flower bulb together (Plot 2).

[0021] According to the normal traditional method in a community, at the beginning of March, 80% of the flower buds on the main flower ball we...

Abstract

The invention discloses a seed production method for reducing the rotting rate of broccoli, and belongs to the technical field of plant cultivation. The method includes the steps: seeding in a proper seeding period of seed production parents; seeding in a potted tray; spreading seeds; performing unified management after seedlings emerge; planting the seedlings on a land for growing field crops with the planting space of 45*40cm after each seedling grows to have four leaves and a center; and cutting off ball flowers and long main stems 15cm below the ball flowers together when the ball flowers of the broccoli grow to have the diameter ranging from 2cm to 3cm. During seeding in the potted tray, the potted tray is filled with matrixes, water is poured over the potted tray, holes are pressed, one seed is placed in each hole, the seeds are covered with the matrixes after seeding, and a small amount of water is poured. During spreading, a flat land with the area of about 10g/m<2> in a greenhouse is selected, special matrixes for raising seedlings are uniformly laid, the thickness of the special matrixes is about 3 centimeters, water is poured over the special matrixes, the seeds are uniformly spread, a layer of matrixes with the thickness of 0.3 centimeter is spread on the seeds again, and then a small amount of water is poured. By the method, the rotting rate of seed production plants of the broccoli can be greatly reduced, the seeds are fine, and the seed yield is improved by more than 50%.

Description

Technical field [0001] The invention relates to a high-yield seed production cultivation method for reducing the decay rate of broccoli, belonging to the technical field of plant cultivation. Background technique [0002] Broccoli is also known as broccoli and green cauliflower. Cruciferous, Brassica, one or two-year-old herbaceous plant. A variety of cabbage with green curd as a product. The green curd formed at the top of the main stem and side branches is the product. Rich in nutrition, good color, fragrance and taste, it is a famous and special vegetable that is very popular in the international market. [0003] The existing broccoli application seeds are all first-generation hybrids, and the market price ranges from 100 per bag to 200 per bag (10g pack). When the vintage is bad, there are even no seeds to buy. In the traditional broccoli seed production, most of the main ball of the broccoli is cut off after the spring (early March), leaving a small half of the flower bu...
