So, when is the planting time of Shandong green onions? How to plant it? What are the planting methods? Let's take a look at it.
Planting time of Shandong Welsh onion 1. Generally speaking, autumn seeds are sown in early September of the first year, planted in the first half of May of the second year, and harvested before winter.
2. When planting in spring and early spring, you can sow when the soil is thawed.
3. Summer sowing in summer sowing is generally from late July to early August every year, which is also called "spring onion".
Shandong Welsh Onion Planting Method 1. There are many varieties of fine varieties of Welsh Onion, and the use of Welsh Onion is very strong. Basically, any seed can grow in any place, which is only related to its yield and quality. Therefore, before planting, we should choose varieties suitable for local climate. We can make a survey on the local Welsh Onion planting situation first, select varieties with high quality and high yield and good market conditions for planting, and then plant multiple varieties in time to check the economic benefits of planting.
2. Soil preparation and fertilization Welsh onion does not have high requirements for planting land. Generally, as long as the light is sufficient and it is close to the water source, it is convenient to irrigate, and the plots with rich organic matter content in the soil can be planted. During soil preparation, 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 the later management will be simpler. Finally, the clods will be broken as much as possible, raked flat, and ditched according to the width of about one meter to one meter and a half.
3. There are three main ways to scientifically plant Chinese onion, namely, plant propagation, ramet propagation and bulb propagation. Generally, the suitable planting time is around May and June every year, and then furrowing or strip planting is carried out at intervals of 30cm per row. The interval between strip planting and each plant is about 5-8cm. Before planting, the planting site must be watered thoroughly, so that the survival rate can be improved by at least about 15%.
4. Fertilization technology The right and wrong of green onions still needs to be decided according to the fertility of the planting area and the growth situation of green onions. Generally, the first fertilization is carried out after beginning of autumn, and according to the normal fertilization situation, about 2000kg of soil mixed fertilizer is needed per mu, or 200kg of cake fertilizer and 20kg of urea can be used, and the second topdressing is carried out after the summer, and this fertilization needs about 15kg of urea. Finally, it depends on the growth of green onions. If the branches and leaves of green onions are thin and mixed, then we need to apply an appropriate amount of potash fertilizer, and add an extremely appropriate amount of fertilizer to each growth of green onions to supplement the nutrients needed for the growth of green onions.
5. Field management will emerge in about 5-6 days after planting, but the temperature in summer is relatively high, and the rainfall is also relatively large, so we should be prepared for flood prevention and drainage, and at the same time, intertillage should be carried out in time after the rain to avoid hardening of the land, and the root system of green onions is relatively weak, so the humidity in the planting area should be kept at least about 75%, and basically there is no need to water too much when the weather is not particularly dry, just need to strengthen.
6. Pests and Diseases Control The most common pests and diseases of Welsh onion are purple spot, onion rust, soft rot, thrips, leaf miner and moth pests. These three common diseases are basically caused by excessive humidity in the field and high temperature, which causes fungi in the field to infect the whole plant of Welsh onion. Generally, chlorothalonil, mancozeb solution and kocide can be used for control, and at the same time, water management and temperature regulation in the field should be strengthened, which is harmful to the growth of Welsh onion.
The above is the information about the planting time and method of Shandong green onions provided by Xiaobian. I hope the above information can help you.
