Cassava planting precautions
Cassava is cultivated all over the world, and cassava has been cultivated in China for more than a hundred years. Its root tuber is rich in starch and is one of the raw materials of industrial starch with high economic benefits. So what should we pay attention to when planting? Let's take a look.
1. Deep digging to improve the soil
One month before planting, soil preparation should be carried out first, covering the soil 30-40 cm, and the sun should be used to whiten it to make it fully weathered and thinned. This is because cassava is a deep-rooted crop, and its roots extend down widely. if the soil is too sticky, it may lead to poor or abnormal root growth, which is disadvantageous to yield and quality. Therefore, it is necessary to prepare the soil and loosen the soil before planting, which is conducive to the increase of its yield. in addition, 250-300 kg of mature farm manure can be applied per mu as base fertilizer.
2. Select improved varieties
In order to obtain high yield, in addition to suitable soil, we should also choose improved varieties with high tuber and high yield, and cassava contains cyanate toxin, so try to choose varieties with less toxicity. The tuber with thick stem nodes, no diseases and insect pests and no damage was selected as the seed stem, and the seed stem should be treated before planting.
3. Fertilization
In order to obtain high yield, fertilization is a very important light. After sowing and emergence, when the seedlings grow to 12-15 cm, it is necessary to apply fertilizer in time, and thin dung water is appropriate to promote the growth of seedlings. In addition to fertilizing the roots of the seedlings, it is also necessary to apply fertilizer around the roots of the seedlings to promote more rooting and accelerate the extension of the roots. When the seedlings grow to 50 cm, topdressing the second fertilizer, in addition to manure, but also topdressing 8-10 kg of urea per mu, preferably mixed with water. After the beginning of autumn, the roots should be exposed, the soil should be exposed for 4-5 hours, and the soil should be cultivated after applying phosphorus and potassium fertilizer.
