Cultivation method for promoting precocity and high yield of broccolis

Abstract

The invention relates to a cultivation method of crops, and particularly relates to a cultivation method of broccolis and the method belongs to the technical field of plant cultivation. According to the invention, on the basis of the existing cultivation technologies, lucifugal low-temperature treatment is carried out on germinated broccoli seeds, so that the green vernalization of the broccolis can be promoted; and on the basis of accelerating each state of the flower bud differentiation, the leafing period is brought forward, benefit is brought to the improvement of photosynthetic products and the aim of promoting the high yield of the broccolis is achieved. The cultivation method has the beneficial effects that simplicity and operability are provided, the mature period of the broccolis can be brought forward by about 3 days, the yield is increased by more than 10% compared with the conventional cultivation, and the comprehensive benefit is higher.

Description

technical field

[0001] The invention relates to a cultivation method of crops, in particular to a cultivation method of broccoli, and belongs to the technical field of plant cultivation. Background technique

[0002] Broccoli (Brassica oleracea L. var. italica), also known as broccoli, green cauliflower, cauliflower, etc., is a primary and secondary herb in the Brassica genus Brassica species with green curd as the product organ. The green curd formed by the main stem and the top of the side branches is the product, which is rich in nutrition, good in color, aroma and taste. It is a famous and special vegetable that is very popular in the international market. Broccoli has a short history of cultivation in my country, but it has developed rapidly. Especially with the improvement of people's living standards and the understanding of the nutritional value and health benefits of broccoli, the demand for broccoli in the domestic consumer market will inevitably double in the futu...

Examples

Embodiment

[0017] Materials: The seeds of broccoli can be selected from the seeds available in the market, such as Ruilu (middle-early-maturing varieties), Jiulu (middle-maturing varieties)—distributed by Zhenjiang Ruifan Agronomy Co., Ltd.

[0018] The present embodiment cultivates broccoli according to the following steps:

[0019] Step 1. Take 600 seeds of Ruilu and Jiulu in mid-July, divide them into two equal parts, and take one part (300 seeds) for seed soaking and germination. After 20 hours, when the seeds begin to germinate (ie When the seeds are white), place the seeds in a refrigerator at 0-2°C (dark conditions) for 15 days;

[0020] Step 2, the seeds after the low temperature treatment and the seeds without treatment are sown with 72-hole plug trays according to the conventional method, and the strong seedlings are grown; , broccoli seedlings with complete cotyledons, dark green leaves, vigorous growth, developed root system, no yellow leaves, and no pests and diseases.
