The latest field management of sorghum

Sorghum is rare in the south, but it is the most basic food crop in the north. Sorghum is one of the largest grain crops in the north of China. Sorghum has been planted in China for a long time, and the planting techniques are relatively perfect. However, it is still necessary to have certain field management skills in the planting process, so today the editor has brought you the field management method of sorghum. Let's take a look at it.

1. Cultivate the soil by ploughing.

Although ploughing and soil cultivation is a necessary work for everyone in planting, many people do not know what the purpose of soil cultivation is. No matter what crops are planted in the first crop of the soil, planting holes are usually used to cultivate them. Therefore, the work of ploughing and soil cultivation is very important, and we should carry out it properly according to the actual growth of sorghum. Generally speaking, the sorghum should be ploughed once after the sorghum planting survived, so as to improve the soil permeability, enhance the fertility and promote the nutrient absorption of the sorghum root. And because the sorghum plant is higher, so when the sorghum reaches the trumpet stage, it is necessary to cultivate the soil in time to prevent excessive growth leading to lodging and affecting the yield of sorghum.

2. Reasonable weeding

Weeds will certainly appear in the sorghum fields. When there are too many weeds in the area, we must weed them in time. Many people will ignore the existence of weeds, leading to the unbridled growth of weeds, the correct nutrients and moisture of sorghum, resulting in sorghum growth hindered and undernourished. Especially when the sorghum is in the seedling stage, the nutrient absorption capacity is very weak and can not compete with weeds. Therefore, we should properly spray herbicides in the seedling stage, spray comprehensively and evenly, and pay attention to the concentration of herbicides to prevent the growth of seedlings.

3. Topdressing in time

Topdressing is an indispensable management work for planting sorghum, and the growth of sorghum needs more nutrition. When we topdressing, we should determine the amount of topdressing according to the growth and varieties of sorghum. If enough fertilizer is applied when the seedlings are transplanted, there will be no need to topdressing when the sorghum returns to green. If no fertilizer is applied, then appropriate topdressing is needed according to the nutritional status. Control the proportion of nutrients in fertilizer, make the nutrition of sorghum more comprehensive, get adequate supply, promote the growth of sorghum and increase the yield.

4. Disease control

Disease control is a work that must be done in every growth period of sorghum, and the management of sorghum land should be strengthened. The growth of sorghum was observed regularly, and the diseased plants were pulled out in time. Do a good job in the prevention of sorghum, improve the disease resistance of sorghum, spray medicine in the field regularly to control diseases and insect pests. The common diseases and insect pests of sorghum are smut, aphids and peach borer, etc., if these diseases and insect pests are not managed in time, they may lead to the failure of sorghum harvest. For farmers, it is not only a waste of a year's time, but also leads to their own loss, so we must pay attention.

The above is a brief introduction to the field management of sorghum. It is common to plant sorghum, but not many people have the right planting method. We should pay special attention to the harm of diseases and insect pests. Previous articles on the website specifically introduce sorghum diseases and insect pests.
