Problems solved by technology

Therefore, transplanting and cultivating soil are indispensable and important links in the growth process of scallions. These two links take up a lot of manpower, and also make the dense planting of scallions a major problem that is difficult to achieve.

Embodiment Construction

[0008] Take Zhangqiu, the main producing area of ​​green onions, as an example. After the previous crops are harvested, the land is cleaned up to remove weeds and sundries in the field. Apply enough basal fertilizer, the basal fertilizer is mainly organic fertilizer. Shallow plowing of 6-10cm, full columbine and rake, and then make a furrow, the width of the furrow is 1-1.5m, and hoe to loosen the soil before sowing. Sow in late September. Before sowing, dry the seeds and soak them with potassium permanganate for disinfection to increase the germination rate and kill pathogenic bacteria. Seeds are newly planted in the same year, sow 1.3-1.5kg per mu, and the sowing should be even. The distance between plants is 3-5cm. Seedlings emerge 7-9 days after sowing. It is not advisable to water before the cotyledons straighten. Water 2-3 times lightly before overwintering. In mid-November, press the frozen water and cover with horse and cow manure or plant ash to protect the seedling...

Abstract

The invention discloses a thick planting method for green onions. The method comprises: sowing seeds precisely according to spacing in rows of 3 to 6 centimeters; when the seedlings are 40 centimeters high, driving timber piles around green onion plots; fixing straw on the timber piles to make a straw mat; fully irrigating and fertilizing the green onions; spraying straw carbon onto the onion plot till the topmost leaf outlet without covering the core leaves; spraying water onto the straw carbon till the straw carbon is wet; afterward moving the straw mat 10 centimeters up every time the leafoutlet grow 10 centimeters; spreading straw carbon on the land till the topmost leaf outlets; spraying water onto the straw carbon till the straw carbon is wet; removing the straw mat in a green onion harvesting season; and harvesting and packaging the green onions and selling the green onions. Compared with the prior art, the method improves planting density by 10 to 20 times, and saves a large amount of land; as transplanting is avoided, lots of labor is saved; and covered by soft straw carbon, the onions only have a small part buried in soil and therefore can be drawn out directly, so the labor for harvesting onions is saved.

Description

technical field [0001] The invention relates to the cultivation technique of green onions, in particular to a method for close planting of green onions. Background technique [0002] In the planting technology of scallions, transplanting is an important link. The purpose of transplanting scallions is to facilitate soil cultivation. When transplanting, it is necessary to make a scallion ditch with a depth of 30 cm and a row spacing of 60-80 cm. Cultivating soil is a unique cultivation technique for scallions. The white onion of scallions is actually the pseudostem, that is, the leaf sheath, and the elongated growth of the leaf sheath cells requires a dark and humid environment. After the soil is cultivated, it can provide conditions for the growth of the leaf sheath. Practice has proved that the deeper the soil, the longer the green onion. Cultivation also plays a role in preventing lodging. Therefore transplanting and cultivating soil are indispensable important links in t...
