Embodiment Construction

[0017] The high-yield planting method of onion of the present invention comprises the following steps.

[0018] 1. Sowing period. Onions are sensitive to temperature and light. Therefore, autumn sowing is very important for the selection of sowing time. It is necessary to cultivate strong and strong seedlings to a certain extent, and to prevent the seedlings from growing too large before winter. Early bolting appeared in the spring of the second year.

[0019] Second, seedbed preparation. The seedbed should choose a field with high terrain, convenient drainage and irrigation, fertile soil, and no onion and garlic crops have been planted in recent years, preferably neutral loam. The amount of base fertilizer in the seedbed should not be too much, to avoid excessive growth of seedlings, fully mix the base fertilizer and soil evenly, and the depth of the cultivated land is about 15 cm. Then rake and plow finely to make a furrow with a width of 2.5 to 2.6 meters and a length of...

Abstract

The invention relates to a high-yield planting method for onions, belongs to the technical field of vegetable planting, and particularly relates to a high-yield planting method for onions. The invention provides a high-yield planting method for onions, wherein the growth vigor of the onions can be controlled and the onions are hardly attacked by diseases. The high-yield planting method for onions comprises the following steps of: I, in a seedling period, as the onions are relatively sensitive to temperature and illumination, and seedlings are prevented from growing too large before winter, bolting appears in advance in spring the next year through a stage of vernalization; II, seedbed preparation: selecting a parcel of rice field which is relatively high in terrain, convenient to drain and irrigate and fertile in soil, and where no crops such as green onions and garlic are planted in recent years as a seedbed, preferably neutral loam; III, grading of seedlings: selecting seedlings which are developed in root system, robust to grow and uniform in size during fixed planting; and weeding out leggy seedlings, dwarf seedlings, diseased seedlings, branched seedlings and seedlings which are too large or too small; and IV, seeding quantity: the seeding quantity is further associated with robustness of the seedlings and bolting in advance; if the density is too great, the seedlings are thin and weak; if the density is too small, the seedlings are too thick, and are easy to bolt.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, in particular to a method for planting onions. Background technique [0002] Onion, alias: bulb onion, onion, jade onion, onion, Dutch onion, leather tooth,. Liliaceae, Allium is a biennial herb. Onions contain prostaglandin A, which can reduce peripheral vascular resistance and blood viscosity, and can be used to lower blood pressure, refresh the mind, relieve stress, and prevent colds. In addition, onion can also remove oxygen free radicals in the body, enhance metabolism, anti-aging, and prevent osteoporosis. It is a health food suitable for middle-aged and elderly people. [0003] Native to Central or Western Asia, onions come in many different varieties and have been used in food all over the world. There are pictures of harvesting onions in ancient Egyptian stone inscriptions in the first millennium BC, and then spread to the Mediterranean region. During the Western Han Dynast...
