What are the precautions for cassava planting? Read this article to understand the key points of cultivation
Cassava is cultivated all over the world, and China has a history of cultivating cassava for over a hundred years. Its tuberous roots are rich in starch and are one of the raw materials for industrial starch, with relatively high economic benefits. So what should be noted when planting it? Let's take a look.
1. Deep plowing and soil improvement
One month before planting, the land should first be prepared by covering the soil to a depth of 30-40 cm, using sunlight to bleach it white so it is fully weathered and loosened. This is because cassava is a deep-rooted crop, and its root system extends widely downward. If the soil is too clayey and heavy, it may cause poor or deformed root growth, which is detrimental to both yield and quality. Therefore, before planting, the land must be prepared and the soil loosened, which helps increase its yield. In addition, at planting time, 250-300 kg of decomposed farmyard manure per mu can be applied as a base fertilizer.
2. Selecting good varieties
To achieve high yield, in addition to suitable soil, you should also select good varieties with high tuber formation and high yield. In addition, cassava contains cyanogenic acid toxins, so try to choose varieties with lower toxicity. Select tubers with thick, dense stem nodes, free of pests and diseases, and free of damage as seed stems. Before planting, the seed stems should be treated before planting.
3. Fertilization
To achieve high yield, fertilization is extremely important. After sowing and emergence, when the seedlings grow to 12-15 cm, topdressing should be applied in time, preferably with thin manure water, to promote seedling growth. In addition to fertilizing at the seedling roots, fertilizer should also be applied around the seedling root zone to encourage more rooting and accelerate root system extension. When the seedlings grow to 50 cm, apply the second topdressing. At this time, in addition to manure water, 8-10 kg of urea per mu should also be applied, preferably dissolved in water and poured on. After autumn begins, the tuberous roots should be exposed and the soil sun-dried for 4-5 hours, and after applying phosphorus and potassium fertilizer, soil should be hilled up.
