Problems solved by technology

[0004] Aiming at the technical problem that early sowing in the conventional cultivation method of Chinese cabbage stalks easily leads to poor growth of seedlings, and the slow seedling time after transplanting is long, which affects the growth of Chinese cabbage stalks, and finally leads to the technical problem that it is difficult to go to the market early. The bolting cultivation method can overcome the high temperature and rainy obstacles of cabbage sprouts in early sowing, combined with the improved seedling raising method and physiological regulation, so that cabbage sprouts can bolt and go on the market early, and improve economic benefits

Abstract

The invention belongs to the technical field of vegetable cultivation, and particularly relates to a cultivation method for promoting early bolting of Brassica campestris L. ssp. chinensis var. utilissen. et Lee. The cultivation method comprises the following steps: (1) building a greenhouse; (2) performing floating seedling-raising; (3) performing land preparation and transplanting; (4) performing growth regulation; (5) performing topdressing application; and (6) performing timely harvesting. Through methods such as reasonably planning the cultivation steps, cooperating with the use of a special seedling-raising substrate, and applying a multi-nutrient fertilizer and a special growth-conditioning solution, the cultivation method has the characteristics that materials are easily obtained and the operation is simple and convenient, can make Brassica campestris L. ssp. chinensis var. utilissen. et Lee perform early bolting and be on the market 5-8 days in advance, is of great significance to meet needs of consumers and improve economic benefits, and has very broad market application prospect.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a cultivation method for promoting early bolting of cabbage sprouts. Background technique [0002] Cabbage stalks are a variety of the subspecies of Chinese cabbage in the genus Brassica in the family Brassicaceae. They are eaten with cabbage stalks and are popular among consumers for their unique flavor. They are one of the important vegetable varieties in winter and spring. The cultivation area of ​​Chinese cabbage sprouts is relatively large, mainly distributed in Hunan, Hubei, Jiangxi, and Guangxi. In the Yangtze River Basin, cabbage shoots are generally sown in September and listed from November to March of the following year. [0003] With the expansion of consumer demand, in order to meet their needs, scientific research and breeding units have bred a batch of early-maturing and high-quality cabbage stalk varieties, such as the "Tiancheng Zaosai ...
