The latest course of rape High-yield cultivation and Management techniques

Rapeseed is a very common leafy vegetable in our daily life. There is a wide planting area in our country. When planting rape, if it is planted on a large scale, then the yield must be very concerned by everyone. Some cultivation management is indispensable if rape is to have high yield. So what exactly is it? The following small series will bring you high-yield rape cultivation management technology, let's have a look together!

1. Prevention of drought

If rape encounters drought after sowing, the germination rate of rape seeds will be greatly affected, resulting in a decrease in rape yield. Therefore, we should water the seedbed frequently after sowing to keep the seedbed soil in a moist state. Before rape emergence, water once a day morning and evening. If it is still dry after emergence, then dilute manure water should be poured in time when the seedling page wilts. However, too much watering is not allowed. If there is much rain, then it is necessary to do a good job in clearing ditches and discharging stains. At the same time, it is necessary to properly sprinkle plant ash to reduce the temperature of seedbeds.

2. Early seedling setting

In the rape seedling stage, in order to avoid excessive seedling density, small growth space affects each other's growth, rob light and so on. To do a good job of thinning seedlings as soon as possible, if thinning seedlings too late, then it will affect the rate of strong seedlings of rape, resulting in yield decline. Therefore, it is generally necessary to enter seedlings at the time of three leaves and set seedlings at the time of five leaves. When thinning seedlings, attention should be paid to keeping strong seedlings and removing weak seedlings. And when thinning seedlings, but also to do a good job of weeding seedbed, to avoid seedbed grass shortage.

3. Timely topdressing

Topdressing is the key to ensure high yield of rape. After the first true leaf appears and spreads flat, topdressing should be applied in time to meet the nutritional requirements of rape growth. Usually one mu should be topdressed with about 1500kg of low concentration human excrement. Then, one week before transplanting seedlings, apply the same amount of decomposed farm manure or about 4 jin of urea. Midway should also be based on the actual growth of seedlings as appropriate topdressing. If the growth is normal, then no topdressing can be used, if there is chlorosis and slow growth, then appropriate urea should be applied.

4. Pest control

Pest control of rape is also very important. At the same time, diseases and insect pests are also one of the main reasons affecting rape yield, especially in the seedling stage of rape. Common pests are aphids, cabbage caterpillar, etc. These pests will cause serious damage to rape leaves, rhizomes and other parts. Therefore, we must use reasonable drugs for prevention and control, and malathion emulsion and other drugs can be used. Then, a week before transplanting, a proper amount of carbendazim, thiophane and other chemicals should be sprayed once to prevent downy mildew and ensure the normal growth of rape.

The above is a simple introduction to the high-yield cultivation and management techniques of rape. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
