Embodiment Construction

[0021] sowing seedlings

[0022] Whole furrow: Onion seedlings are afraid of water before the 3-leaf stage. According to this feature, the width of the furrow is 1m, the length of the field is the length of the furrow, and furrows are left instead of high furrows to facilitate drainage.

[0023] Fertilization: Miaoqing requires fertile soil. Apply 3000kg of decomposed soil and miscellaneous fertilizers, 10kg of urea, 7kg of diammonium phosphate, and 15kg of potassium sulfate per mu. Spread evenly, plow deep and rake finely, so that the soil is empty on the top and solid on the bottom.

[0024] Sowing: Before and after the "grain rain" in spring, summer propagation is generally from late May to early June. The sooner the stubble comes out, the better. Generally, sowing is used. First, a layer of soil is formed in the furrow, and after sieving, it is used as a cover. Then, enough base fertilizer is applied to the furrow, the furrow surface is leveled, and the bottom water is fil...

Abstract

The invention discloses a seed reproduction and high-yield cultivation technical specification of onion, which aims at providing the seed reproduction and high-yield cultivation technical specification of the onion against the problem that the prior seed reproduction of the onion is lack of the quipped cultivation technical measures, so that the seed production is low and unstable. The seed reproduction according to the specification has the advantages of simple and scientific cultivation method, high seed production, labor-saving property, low cost, stable seed nature and high purity.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a high-yield cultivation technical regulation for scallion propagation. Background technique [0002] Green onion seeds have a short lifespan, only one or two years under normal storage conditions. Therefore, scallion seed production is an important link in scallion production. At present, the market demand for scallions has increased sharply, and the cultivation area of ​​scallions has continued to increase, requiring a large amount of planting. So far, there is no complete set of technical regulations for high-yield cultivation of scallions. Seed collection using semi-adult plants is a method of collecting fine varieties of green onions that has been widely used in production in recent years. This method of seed collection has the advantages of high yield per unit area, short land occupation time, low cost, and labor-saving advantages. However, due ...
