A kind of industrialized seedling raising method of green onion

Abstract

The invention discloses an industrialized seedling culture method for Chinese onions. A seedling shed is set up according to a conventional method, a seedbed is arranged in the seedling shed, soil in the seedbed is leveled, and ridges are formed. The method specifically includes the following steps of firstly, laying gauze on the seedbed; secondly, filling a nursery seedling plate with a matrix; thirdly, pre-processing seeds before sowing; fourthly, sowing the seeds; fifthly, conducting film mulching; sixthly, managing the seedbed; seventhly, conducting disease control at the seedling stage; eighthly, improving the growth of roots and seedlings. When Chinese onion seedling culture is conducted through the seedling culture technology, the number of seeds which are used is small, seedling emergence is quick, seedlings are robust and resist diseases, root systems are developed, the environment can be artificially controlled for industrialized seedling culture, mechanical transplantation is facilitated, seedling recovery is quick after transplantation, seedling lands are saved, the seedling culture cost is greatly saved, and good development prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural seedling cultivation, in particular to a method for industrialized seedling cultivation of green onions. 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. At present, the seedling raising technology of scallions in our country is still quite backward, and the traditional open-air seedling raising method is still mainly adopted in the field, and the seedlings are raised through a series of links such as seed sowing, seedling picking, and seedling picking. With this seedling raising method, it is greatly affected by natural conditions. The onion seedlings bred are uneven, the uniformity of the onion seedlings is low, the buds are weak, and weeds are also mixed in. The utilization rate of the onion seeds is only 65% ​​to 70%. Moreover, 170 mu of seedling land is...

AI Technical Summary

Problems solved by technology

With this seedling raising method, it is greatly affected by natural conditions. The onion seedlings bred are uneven, the uniformity of the onion seedlings is low, the buds are weak, and weeds are also mixed in. The utilization rate of the onion seeds is only 65% ​​to 70%. Moreover, 170 mu of seedling land is required for planting per thousand mu. Affected by natural conditions and soil-borne diseases, it is difficult to breed strong seedlings without pests and diseases, and its root system is not well developed. After planting, the seedlings are slow and the growth cycle is long, which directly affects the green onion. output and quality

In addition, the traditional seedling raising method cannot realize mechanized production. The link from seedling raising to transplanting mainly depends on manual work, which requires a lot of labor, high labor intensity, time-consuming and labor-intensive, and low efficiency.
