Spring seedling culturing method for green Chinese onions

Abstract

Small sheds are adopted for carrying out seedling cultivation for green Chinese onions in the Spring, high-quality seeds are selected, a seed bed is well maintained, sufficient water and fertilizer are applied, bud forcing treatment is carried out on the seeds, then fine earth with 20-30 times of the weight of the seeds is evenly mixed with the seeds, and the seeds are sown in the middle ten days of the March. Sufficient water and fertilizer are applied in a growing period, weeds in the seed bed are removed, ventilation and cooling are carried out when the temperature in the small sheds reaches 35 DEG C, and the temperature in the small sheds is maintained between 25 DEG C to 35 DEG C. Hardening of seedlings, exercising the seedlings and strong seedling promotion are carried out in the middle ten days of the May. According to investigation and statistics, the average stem diameter in the spring seedling process is 0.9cm, the average plant height is 55cm, the average root length is 10cm, the average number of roots is 29, the average stem length of the green Chinese onions is 3cm to 4cm, the rate of seedlings of the first grade reaches more than 80%, the average yield per mu is 2825 kg after transplantation, the average unit price is one yuan, and the average income per mu is 2825 yuan. The spring seedling cultivation for the green Chinese onions enables the seedling cultivation for the green Chinese onions to develop towards double-season and diversification modes, planting time is short, cost is low, and time and labor are saved. The spring seedling cultivation can provide sufficient green Chinese onion seedlings of high quality, and the industry of the green Chinese onions is made to be developed stably and continuously.

Description

technical field [0001] The design of the present invention is a method for growing seedlings of scallions in spring. Background technique [0002] Raising green onion seedlings is the basis of green onion cultivation, and cultivating strong seedlings is a prerequisite for high yields of green onions. Green onion seedlings across the country mainly adopt autumn seedlings, which are usually sown in mid-to-late September, transplanted and planted in May-June of the following year, and the growth period is as long as 9-10 months. The growth period is long, the production cost is high, and field management is difficult. Affect the development of green onion industry. Spring seedlings can promote the double-season and diversified development of scallion seedlings, provide sufficient and high-quality scallion seedlings for scallion production, and enable the scallion industry to develop stably and sustainably. Contents of the invention [0003] In order to solve the technical d...
