Onion cultivation method

Abstract

The invention relates to an onion cultivation method. At present, onion production has many problems, normal growth and development of onions are affected, and the yield is difficult to improve. The method comprises the steps that onions are cultivated in a ridge field being 4 meter, five semicircular ridges are made, the semicircular ridge radius, namely, the ridge height is 40 cm, the semicircular ridge diameter, namely, the ridge width is 80 cm, each semicircular ridge is planted with 9 seedling strips of the onions, the arc length of each semicircular ridge is 125 cm, the distance of cambered surfaces between the seedling strips is 13 cm, the plant spacing is 13 cm, the height difference between the seedling strips is 10 cm, 45 rows of the seedling strips of onions are actually planted in the standard 4-meter ridge field, and compared with a horizontal load, 3 rows of the seedling strips are added for each ridge; for the horizontal load, 38,432 plants are planted, each ridge has 6 seedling strips, and a 4-meter ridge field has 30 seedling strips; 15 rows of the seedling strips are added for the 4-meter ridge field, each pit is planted with one plant, 57,649 plants are planted by adopting the semicircular ridges per acre, and 19,217 plants are added per acre.

Description

technical field [0001] Agricultural planting industry onion cultivation method. Background technique [0002] At present, there are many problems in onion production, such as blind and random fertilization, resulting in too much or too little fertilization, which affects the normal growth and development of onions. Some onion farmers are used to planting old onion varieties with low quality and low yield. Some onion farmers are not timely and thorough in the prevention and control of onion pests and diseases. Some onion farmers have the phenomenon of heavy planting and light management, resulting in inadequate inter-cultivation management. Some are sown too early, the onion seedlings are too large, prone to low-temperature vernalization, and the onion bolts early, and some are sown too late, the seedlings are weak, the growth is delayed, the bulb expansion period is shortened, and the yield is low. The traditional method of planting flat ridges and flat loading has low de...

Problems solved by technology

Some onion farmers are not timely and thorough in the prevention and control of onion pests and diseases

Some onion farmers have the phenomenon of heavy planting and light management, resulting in inadequate intertillage management

Some are sown too early, the onion seedlings are too large, prone to low-temperature vernalization, and the onion bolts early, and some are sown too late, the seedlings are weak, the growth is delayed, the bulb expansion period is shortened, and the yield is low

The traditional method of planting flat ridges and flat loading has low density, low utilization rate of three-dimensional space, and difficult to increase yield
