Cassava has strong adaptability to soil, drought resistance and barren resistance.However, the weak acid soil with loose soil and deep soil layer below 2000 meters above sea level in subtropical and tropical areas is better.Usually, soil should be loosened frequently to maintain soil permeability.
The requirement for light is high, and sufficient light should be ensured every day.Under the condition of insufficient light, the stem is thin, the internode and petiole are long, the leaf is thin, and the flower bud is poorly developed.However, in the high temperature and strong light season of July and August, appropriate shading should be considered to avoid sunburn and affect the quality of fruits.
The best annual temperature for its growth is about 27 , and it likes warm climate.At about 10 , the growth tended to be slow, the young organs began to freeze at 5 , and the leaves withered at 0 .Too high temperature is also harmful to growth and development.
Newly loaded cassava is not suitable for immediate irrigation, only need to spray water to make the soil slightly moist.Keeping the surrounding environment moist is conducive to its growth, and water should be sprinkled in time during the dry period of summer.Attention should be paid to drainage and water should not be accumulated for too long.
Because its growth needs more nutrients and trace elements such as CA and K, it needs to apply thin fertilizer once a month.It is recommended to use diluted livestock manure or decomposed cake fertilizer.
1. Intertillage and weeding should be carried out 4-5 times throughout the year to increase soil permeability and nutrient supply, so as to help it grow.
2. The main insect pests are red spider and snail.Pesticides should be sprayed regularly and regularly for pest control.
