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. [0003] Potato (scientific name: Solanum tuberosum L.), genus Solanaceae , an annual herb, tubers Available edible , the world's fourth most important food crops ,second only to wheat , rice and...

AI Technical Summary

Problems solved by technology

There are many reports on the rotation of onion and other crops, but there is no relevant report on the rotation of onion and potato to prevent late blight

[0005] The onion seed collection cycle is long, the life of the seeds is short, and the years of seed production vary greatly. The instability of seed production often affects the planting area in production, and the quality of seeds is directly related to the economic interests of producers. Therefore, How to adopt appropriate seed collection methods and techniques is crucial to the stable yield and quality improvement of onion seeds
