Field Management of Sorghum

Sorghum is rare in the south, but it is the most basic food crop in the north. Sorghum cultivation is one of the largest crops in northern China. Sorghum planted in our country has a very long time, and the planting technology is relatively perfect. However, there must be certain field management techniques in the planting process, so today Xiaobian brings you the field management methods of sorghum. Let's take a look below!

1. Cultivation

Although cultivation is a necessary part of planting, many people do not know what the purpose of cultivation is. No matter what crop is planted in the soil before, it is usually planted in holes. Therefore, the work of cultivating soil is very important. We should carry out it properly according to the actual growth of sorghum. Generally, after sorghum planting survives, it is necessary to immediately cultivate deeply to improve soil permeability, enhance fertility and promote nutrient absorption of sorghum roots. And because sorghum plants are relatively high, so when sorghum reaches the bell mouth stage, it should be cultivated in time to prevent high growth from causing lodging phenomenon of sorghum and affecting yield.

2. Reasonable weeding

Weeds will definitely appear in sorghum fields. When there are too many weeds in the fields, we must weed them in time. Many people will ignore the existence of weeds, resulting in uncontrolled growth of weeds, correct sorghum nutrient moisture, resulting in sorghum growth stunted, nutritional deficiency. Especially when sorghum is in the seedling stage, the nutrient absorption capacity is very weak, completely unable to compete with weeds. Therefore, we should spray herbicides properly during the seedling stage. When spraying, we should spray them evenly and pay attention to the concentration of herbicides to prevent inhibition of seedling growth.

3. Timely topdressing

Topdressing is an essential management for sorghum cultivation, and sorghum growth requires greater nutrition. When we topdressing, we should determine the amount of topdressing according to various factors such as sorghum growth and variety. If sufficient fertilizer is applied at the time of seedling transplanting, no topdressing is needed at the time of sorghum rejuvenation. If fertilizer is not applied, then appropriate topdressing is required depending on the nutritional situation. Control the proportion of each nutrient in the fertilizer, so that the nutrition of sorghum is more comprehensive, get sufficient supply, promote the growth of sorghum, and improve the yield.

4. Disease control

Disease control is a must in sorghum every growth period to do a good job, to strengthen the management of sorghum land. Regular observation of sorghum growth, found that there is a disease phenomenon in time to pull out the diseased plants. Good sorghum prevention work, improve sorghum disease resistance, regular spraying of comprehensive field, pest control. Sorghum common diseases and insect pests and smut, aphids and peach borer, etc., these diseases and insect pests do not manage in time, then may lead to sorghum harvest. For farmers, it not only wastes a year's time, but also leads to their own loss, so everyone must pay attention.

The above is a simple introduction to sorghum field management. It is common to plant sorghum, but there are not many people who have completely correct planting methods. Everyone should pay special attention to the harm of diseases and insect pests. Previous articles on the website have specifically introduced sorghum diseases and insect pests.
