Castor is now grown on a large scale in 30 countries around the world. China is also one of the main castor growing countries. Planting castor needs to be managed by everyone, so how to manage it? Let's take a look at the field management skills of castor with the editor.

1. Cultivate the soil with seedlings.

Observe the growth of the seedlings, when the castor seedlings grow to about 9 cm, the seedlings should be properly separated, the seedlings that are too weak and too dense should be pulled out, and then the healthy castor seedlings should be replenished and carried out together with soil cultivation. When the castor grows to about 18 cm, the seedlings can be fixed, leaving a strong seedling in each planting hole, and then ploughing the soil again after fixing the seedlings. And when it is about to blossom, cultivate the soil for the last time, fix the castor plant, promote the growth of the root, and play the role of wind resistance and lodging resistance.

2. Core extraction and plastic surgery

In the process of castor growth, in order to prevent the overgrowth of the plant, the tip of the main stem should be cut off when the castor grows 9 true leaves. Then, according to the growth of castor, the tip of the branch was cut off properly to promote the growth of the branch and increase the yield. Control the height of the plant to facilitate later harvest. When the plant is taller and there are more branches, we should pay attention to pruning and pruning. Promote the generation of new branches and control diseases and insect pests, do not break branches when pruning, to prevent other damage to the plant. After pruning, topdressing should be done well, water management should be strengthened and plant growth should be promoted.

3. Overwintering management

Perennial castor plants should be ready to survive the winter after harvest. In snowy areas, castor plants should be wrapped up with straw and removed in spring. If there are plants that have suffered from frost injury, the part of the freeze injury should be cut off, the wound should be disinfected after cutting, and then it should be wrapped in poultry droppings. When the temperature picks up in spring, it will sprout again. In areas with lower temperatures, the main stem should be cut off before winter, and then the aboveground part should be wrapped in feces. Buried in the soil, when the snow gradually melts and the temperature rises, it can sprout and grow branches.

4. Disease control

The prevention and control of diseases and insect pests of castor is very important, the most common diseases and insect pests of castor are Fusarium wilt and small land tiger and so on. When we plant, we must pay attention to the prevention and control of diseases and insect pests, no matter what diseases and insect pests, the damage to castor is very great, serious will lead to no harvest in the whole land. Regular observation of the growth of castor, to achieve early detection of diseases and insect pests early treatment, to avoid greater losses. Prepare drugs to treat all diseases and insect pests and be foolproof.
