The key points of the latest field management of lentils

Lentil is a perennial twining vine, which has a certain planting area in tropical areas all over the world. The pods and flowers of lentils are edible and have various effects such as invigorating the spleen and stopping diarrhea and regression of tumors. It is a kind of vegetable with high economic value, so how should we manage it when growing lentils? The following editor brings you the key points of the field management of lentils, let's have a look!

1. Plant adjustment

Because lentils are a kind of vine, we should do a good job of setting up frames after lentils survive. Lead the vine to the stake and set up the frame according to the reasonable distribution of the row spacing of the lentil plant. Fix the pile top to avoid being blown down by the wind, and then connect the nearby pile top with iron wire. It is convenient for lentil to climb and grow and satisfy the growth habit of lentil fence. After entering the growing period of lentils, we should pay attention to control the number of leaves on the lentil plant. Remove bad leaves such as overdense, old and weak leaves, diseases and insect pests in time. Avoid excessive nutrient consumption, improve ventilation in the plant, and promote the growth of lentil pods.

2. Temperature management

Lentils have certain requirements on temperature in their growth. When planting lentils, we should adjust the temperature reasonably according to the growth stage and growth of lentils. For example, in the lentil flowering and podding period, the temperature should be controlled at 17-26 degrees, and about 20 degrees is the best temperature. Too high and too low temperature will have a great impact on the flowering and podding of lentils. When the temperature is higher than 31 degrees, it will cause lentils to increase the phenomenon of falling flowers and pods and reduce the quality. Therefore, when the temperature is too high, it must be ventilated and cooled in time, on the contrary, when it is too low, we must do a good job of keeping warm.

3. Fertilizer and water management

After transplanting and planting lentils for about 3 weeks, nitrogen fertilizer and compound fertilizer should be applied properly to promote the growth of seedlings. Then in the lentil flower and pod period to control the amount of water and fertilizer, it is best not to apply. Wait until the first inflorescence sits on the pod before starting to work on water and fertilizer. If there is film mulching, then watering is best under the film, combined with mature farm manure. When applying nitrogen fertilizer, we should pay attention to the use of ammonia nitrogen. Excessive use of ammonia nitrogen will hinder the growth of lentils. Therefore, when topdressing nitrogen fertilizer, it is best to give priority to nitrate nitrogen, and control the amount of nitrogen fertilizer to avoid fertilizer damage.

4. Pest control

Diseases and insect pests will have a great impact on the yield and quality of lentils. When planting lentils, we must pay attention to the prevention and control of diseases and insect pests. The common diseases and insect pests of lentils are virus disease, rust, small gray butterfly and so on. They will harm different parts of lentils to varying degrees, resulting in lentil growth hindrance. Therefore, we should try our best to understand the common diseases and insect pests of lentils, grasp the symptoms of the disease, so that the specific condition can be detected in time, and then make corresponding prevention and control work. Do not use drugs blindly to prevent drug damage, but also affect the growth of lentils.

This is a brief introduction to the field management of lentils. The management of lentils is very important. When planting, the management directly determines the yield and quality of lentils, so we must pay more attention to it! That's all for today's introduction. This article is for reference only.
