A detailed explanation of the latest key points of castor field management techniques
Castor is a very important oil crop in our country. The oil pressed from castor seeds has high viscosity, tolerates both low and high temperatures, and can maintain its original state without deforming under low and high temperatures. Castor is now cultivated on a large scale in 30 countries around the world. Our country is also one of the main castor-growing countries. Growing castor requires everyone to do a good job in management, so how should castor be managed when growing it? Now let's take a look together with the editor at the field management techniques for castor!
1. Thinning seedlings and earthing up
Observe the growth of the seedlings. When castor seedlings grow to about 9 cm, they should be appropriately thinned, removing the weak and overly dense seedlings, then filling in with healthy castor seedlings, and this should be done together with intertillage and earthing up. When castor grows to about 18 cm, the seedlings can be fixed, leaving one strong-growing seedling in each planting hole, and after fixing the seedlings, carry out intertillage and earthing up once more. Also, when it is about to flower, carry out the last intertillage and earthing up to stabilize the castor plant, promote root growth, and play a role in resisting wind and lodging.
2. Pinching and shaping
During the growth of castor, in order to prevent excessive vegetative growth, when castor grows 9 true leaves, promptly cut off the top of the main stem. Then, according to the growth of the castor, appropriately cut off the tops of the branches to promote branch growth and increase yield. Control the height of the plant to facilitate later harvesting. When the plant is relatively tall and has many branches, pay attention to doing a good job of pruning and shaping. To promote the production of new branches and prevent and control pests and diseases, do not break off branches when pruning, to prevent other damage to the plant. After pruning, do a good job of topdressing and strengthen water management to promote plant growth.
3. Overwintering management
For perennial castor, preparations for overwintering should be made after harvesting. In areas with snow, wrap the castor plants with straw and remove it in spring. If any plants have already suffered freeze damage, cut off the damaged parts, disinfect the wounds after cutting, and then wrap them with poultry manure. After temperatures rise in spring, they will sprout and emerge again. In areas with lower temperatures, cut off the main stem before winter, then wrap the aboveground parts with manure. Bury them in the soil, and after the snow gradually melts and temperatures rise, uncover them, and they can sprout and grow branches.
4. Disease control
The prevention and control of pests and diseases in castor is very important. The most common pests and diseases of castor include wilt disease and black cutworm, etc. When planting, we must pay attention to doing a good job in the prevention and control of pests and diseases. No matter what kind of pest or disease it is, the harm to castor is very great, and in severe cases it can lead to no harvest from the entire field. Observe the growth of castor regularly, and achieve early discovery and early treatment of pests and diseases to avoid greater losses. Prepare medicines for treating all pests and diseases to ensure nothing goes wrong.
That is all for today's introduction. Castor is somewhat toxic, so avoid eating castor. The younger the age, the higher the possibility of poisoning, so everyone must pay attention, prevent children from eating it by mistake, and strengthen management.
