Method of raising Allium fistulosum seedlings by using seed belt

Abstract

The present invention relates to the technical field of Allium fistulosum cultivation, in particular to a method of raising Allium fistulosum seedlings by using a seed belt, including: after land preparation and fertilizer application, sowing seeds by means of manual ditching with a seed belt seeder, wherein seeding depth of the seed belt is 3-4 cm, seed spacing is 2 cm, row spacing is 8-15 cm, and seeding is carried out with single grains; after seeding, earthing, leveling, flattening, and irrigating with sufficient seeding water; performing management in a seedling stage. The seed belt seedling-raising technology overcomes the defects in large field broadcasting cultivation and seedling tray cultivation and is a seedling raising method that is low in input cost, high in seedling emergence rate, capable of implementing uniform and robust seedlings, free of manual seedling selection in later stage and low in cost; by using the seed belt seedling-raising technology, seedling and stalk length is greater than that of seedlings raised with seedling trays and broadcasting, and plant height is also better.

Description

technical field [0001] The invention relates to the technical field of scallion cultivation, in particular to a method for growing scallion seedlings using seed tapes. Background technique [0002] The high-white scallions represented by Zhangqiu scallions have a large-scale planting area of ​​more than 740,000 mu in Shandong Province, accounting for more than 80% of the province’s scallion cultivation area. It is planted in some areas of Jiangsu Province, Inner Mongolia, Qinghai Province and other places. Zhangqiu scallion, a unique variety, has a planting area of ​​more than 150,000 mu in Zhangqiu City and surrounding areas, and occupies a leading position in the scallion industry in Jinan City and even our province. Zhangqiu scallion seedlings generally adopt the mode of sowing seedlings in the field in autumn and transplanting in the next summer. Traditional scallion seedlings are mainly raised by direct seeding in the field. In some areas, protected cultivation techni...

Problems solved by technology

The green onion greenhouse seedling cultivation technology is relatively mature in Japan and other countries, and industrialized seedling cultivation and mechanized production have been carried out. However, the green onion varieties grown in Japan and other countries have shorter whites than Zhangqiu green onions, which are different from Zhangqiu green onions to produce high-quality products with light whites above 60cm With the fine planting mode mainly of scallions, the seedling raising technology of Japan and other countries cannot be directly used by grafting in the main production area of ​​Zhangqiu scallions

In China, the Institute of Vegetables, Shandong Academy of Agricultural Sciences has done experiments on the cultivation of green onion seedlings in plug trays. The height of the seedlings bred is about 30 cm, and the diameter of the green onion seedlings is slender, which is 50-70 cm tall compared with the seedlings bred by conventional field seedling raising techniques. In comparison, the seedlings are smaller and grow slowly after being transplanted into the field. In addition, the amount of seedlings per mu of scallions is large, and 128-mesh plugs are used for seedling cultivation. About 200 plugs are needed per mu, and the cost of plug seedlings is relatively high. Difficult to promote

[0004] At present, Zhangqiu scallion adopts field sowing seedling raising technology. First, the amount of seeds used is relatively large. One mu of seedbed uses 3-5 catties ​​of scallion seeds, which increases the cost of seeding. The proportion of weak green onion seedlings is large, resulting in the waste of green onion seedlings; the third is the long growth period of field sowing seedlings, generally about 270 days, resulting in waste of land resources; the fourth is field sowing seedlings, which requires a large cost of artificial seedling selection

Green onion plug seedling technology increases the cost of plugs and seedling substrates, increasing the cost of seedlings
