What is the planting time and method of castor? How to achieve high yield?

In recent years, the number of people planting castor has obviously increased, because many people see that its planting prospects are very broad, so I will talk about the planting time and method of castor today. If you are interested in it, come and have a look!

Planting time and method

1, soil preparation and fertilization

After the previous crop is harvested, plough and apply organic fertilizer before freezing. In the middle and late March, nitrogen and phosphorus compound fertilizer was applied, and the land was plowed twice. You can't use low-lying and waterlogged land. Ricinus communis has strong adaptability to soil, drought resistance and alkali resistance. Generally, soil can grow as long as it is well drained, but fertile soil is better and the requirements for previous crops are not strict.

Step 2 choose good seeds

Dry land and thin land can be used as castor 1, castor 1 and 2; Ricinus communis No.3, Ricinus communis No.2 and Ricinus communis No.3 can be used in fields with high water and high fertilizer.

3, timely sowing

Before sowing, seeds should be selected and dried to improve the germination rate. Spring sowing should be as early as the beginning of April, and wheat interplanting should be held in the middle of April. If wheat is harvested by machine, sowing can be postponed until the end of April. Generally, manual digging is used, and 3 seeds are planted in each hole. When covering the land with clay, it is not recommended to press the soil.

4. Reasonable close planting

The sowing amount per mu of castor seeds should not be controlled.

5. Fertilizer and water

Ricinus communis seedlings generally do not need to be watered, and the main stem spike can be properly watered when it is particularly dry after flowering. Fertilization should be carried out at the flowering stage of branches and ears, and generally effective urea 10 ~ 20 kg is applied per mu. No fertilization during the branching period.

6, chemical control and full branch

After the flowering of castor, chemical control should be carried out at the early stage of branch growth according to soil water content by spraying paclobutrazol solution. If wheat is sown, the branches should be removed in early September to ensure that the young fruits are fully mature at the beginning of 10.

7. Cultivate soil to prevent floods

Castor is particularly resistant to flooding, so field drainage is the key to the success of planting castor in the field. Generally, after the main stem spike is formed in late June, combined with root cultivation, deep ditches are dug between rows, so that self-drainage ditches are formed between rows and connected with the ground edge of the ditches.
