The latest planting method of green onion

It can be said that the most famous green onion in China is the green onion in the northeast. One of the important factors is that green onion is a heavy-tasting food for northeastern people. They like to eat raw green onions and drink in large bowls. Moreover, the technology of planting green onions in Northeast China is also very perfect. The green onions planted are big, white and tender, so today let's take a look at the planting technology of green onions.

1. Select improved varieties

There are many varieties of green onions, and they are very useful to the environment. Basically, any seed can grow in any place, but it is related to its yield and quality. Therefore, before planting, we have to choose varieties suitable for the local climate. We can first make a survey on the local green onion planting situation, and choose varieties with high quality and high yield and good market conditions to plant. Secondly, multiple varieties can be planted in time to check the economic benefits of planting, and then select the best.

2. Soil preparation and fertilization

Green onions do not have high requirements for planting land, generally as long as the light is relatively sufficient, and close to the water source, it is convenient to irrigate, and plots rich in organic matter in the soil can be planted. When preparing the soil, it is necessary to dig at least 30 centimeters deep, and clean up the impurities in the soil, such as pest residues and weed roots, so that later management will be relatively simple. Finally, the clods will be broken as much as possible, and then raked flat, at the same time according to the width of 1 meter to 1.5 meters or so to open a ditch to make a bed can wait for planting.

3. Scientific planting

There are three main ways to plant green onions, namely, planting reproduction, ramet reproduction and bulb propagation. The suitable time for planting is generally from May to June every year. Then, strip sowing or strip planting is carried out according to the interval of 30 cm per row. The interval between each plant is about 5 to 8 cm. Before planting, the planting land must be watered thoroughly, so the survival rate can be increased by at least 15%.

4. Fertilization technology

The right and wrong of green onions mainly depends on the fertility of the planting land and the growth of green onions. Generally speaking, the first fertilization is carried out after the Beginning of Autumn. According to the normal fertilization situation, about two thousand kilograms of soil and miscellaneous fertilizer per mu is needed, or two hundred kilograms of cake fertilizer and twenty kilograms of urea can be used. After the summer heat everywhere, the second topdressing is carried out, and this fertilization requires about 15 kilograms of urea. The last is to look at the growth of green onions, if the branches and leaves of green onions are relatively thin, but also more miscellaneous inverted hook situation, then we also need to apply an appropriate amount of potash fertilizer. And in each growth of green onions extremely appropriate amount of fertilizer, but also supplement the nutrients needed for the growth of green onions.

5. Field management

Seedlings will not emerge about five or six days after planting, but the temperature in summer is relatively high, and the rainfall is also relatively large, so we should be prepared for waterlogging and drainage, and ploughing should be carried out in time after rain to avoid consolidation of the land. The root system of green onion is relatively weak, so the ten degrees in the planting land should be kept at least about 75%, and there is basically no need for too much watering when the weather is not particularly drought. it only needs to strengthen the management of soil permeability and weeding in the field.

6. Pest control

The most common diseases and insect pests of Welsh onion are purple spot, onion rust, soft rot and thrips, leaf miner and moth pests. These three common diseases are basically due to excessive humidity in the field, coupled with relatively high temperature, leading to the production of fungi in the field, thus infecting the whole plant of Welsh onion and causing the disease. We can generally use chlorothalonil, manganese zinc substitute and Shixiao to control. At the same time, water management and temperature regulation in the field should be strengthened. On the other hand, the pests that harm the growth of Welsh onions can be sprayed with imidacloprid, avermectin and methamectin.
