Onion crop rotation planting method

Abstract

The invention discloses an onion crop rotation planting method, and relates to the field of agriculture. According to the onion crop rotation planting method, crop rotation of onions and potatoes canbe achieved, late blight is prevented, and a method for improving the onion yield by improving an onion seed selection manner and an irrigation manner is provided. According to the onion crop rotationplanting method, the potatoes are continuously planted on land where the onions are planted in a manner of crop rotation of the onions and the potatoes, generation of disease bacteria in soil can bereduced, and therefore the probability of the late blight in potato planting in the next year is reduced. Through onion variety breeding, a variety with high purity and species can be obtained, diseases are effectively reduced, and the yield is increased. According to the method, a low-pressure drip irrigation belt for water-saving irrigation is adopted for drip irrigation, water can be effectively saved, the drip irrigation amount is controlled, the sufficient water amount can be guaranteed, growth of the onions can be guaranteed, and watering can be controlled to prevent excessive growth. The adopted drip irrigation belt can achieve the uniformity of the water outlet speed and the uniformity of irrigation. The onion crop rotation planting method is applied to the field of crop planting.

Description

technical field

[0001] The invention relates to the field of agriculture, in particular to a method for planting onions in rotation. Background technique

[0002] Onion, also known as bulb onion, round onion, jade onion, onion, Holland onion, Liliaceae Allium, is a 2-year-old herb plant, the planting distance is generally 60×30cm, it grows upright, about 1.5m high, and is composed of leaf sheaths. Stem", umbel, with 200-1300 flowers, cross-pollination, capsule. Mature seeds are shield-shaped, black, with a thousand-grain weight of 3 to 5 grams, and a useful life of one year. Onions are widely distributed in my country, and are cultivated in all parts of the north and south, and the planting area is still expanding. It is currently one of the main vegetables in my country.

Embodiment 1

[0032] A kind of rotation planting method of onion of the present embodiment is carried out according to the following steps:

[0033] Step 1. Select fertile and water-conserving and fertile plots in Lanxi County, Heilongjiang Province, apply 3000-5000 kg of decomposed and sterilized organic fertilizer, 100 kg of potassium sulfate compound fertilizer, and 20 kg of urea per 6 mu of land; then plow, The plowing depth is 25 cm, the ridge width is 40 cm, the ridge width is 180 cm, and the planting width is 210 cm;

[0034] Step 2, select the onion after screening (the variety is Kongzhi yellow, black registration 2005033) as the variety to be sown, sprinkle 1 kg of Dichongjing into every 6 mu of land before sowing, and suppress it flatly, and spray 100% of Dichongjing in the field. ml;

[0035] Step 3: Select 45 days before the local average temperature drops to 15°C for sowing, with a seeding rate of 5 kg per mu, broadcast on the furrow surface, and then cover with soil;
