Detailed Explanation of Key Points of Cassava Field Management Techniques
You may not have eaten cassava, but you are certainly familiar with cassava flour. The bread and other foods we eat every day contain a great deal of cassava flour, and cassava is mainly used as the primary raw material for various industrial starches. At present, the cassava planting area is relatively large, but there are still some people who do not know how to manage it. Cassava has different management methods at each growth stage, so today the editor has brought you the management methods for the different growth stages of cassava. Let's take a look below!
1. Seedling stage management
Cassava is relatively fragile during the seedling stage. When the surrounding temperature is 20 degrees or above, cassava can generally germinate and emerge in about a week. The two months after emergence are the period of the most vigorous root growth in cassava, but the plant's growth capacity decreases during this period. The nutrients for seedling growth are mostly provided by the nutrients stored in the stem, and root growth and rooting also require a certain amount of nutrients. Therefore, during the seedling stage, it is necessary not only to control the temperature well, but also to increase fertilizer supply to promote seedling growth and prevent planting failure caused by insufficient nutrients.
2. Tuberous root formation stage
The tuberous root formation stage is generally about 2-3 months after planting, and this period is also the vigorous growth period of cassava, with the number of tubers increasing greatly. After 3 months, the tuberous root growth of cassava has basically taken shape, and generally each plant will have about 7 tuberous roots. The growth rate of stems and leaves accelerates, and branching also begins to appear at the top. Tuberous root formation is greatly related to soil fertility and the surrounding environment. When the soil is fertile, loose and deep, and the humidity is normal, it is beneficial to tuberous root formation. If the soil is compacted, it will affect the tuber-setting amount and quality of the tuberous roots.
3. Tuberous root enlargement stage
After the tuberous root formation stage comes the tuberous root enlargement stage, which is the most important stage in the growth of cassava. This is because at this time cassava has a very strong capacity for stem and leaf growth, the number of new leaves is extremely large, and the demand for nutrients is also greatly increased. To meet the nutrient demand during the enlargement stage, if there are insufficient nutrients, the enlargement of the tuberous roots will be hindered, which has a very great impact on quality. After the enlargement stage, the old leaves will gradually fall off automatically, and then the enlargement of the tubers will gradually be completed. When the leaves have all fallen, the tuberous root enlargement stage will also gradually end.
4. Tuber maturity stage
After the enlargement stage naturally comes the maturity stage. The maturity stage of cassava is usually around 10 months. After normal and reasonable planting management in the early stage, the tuberous roots have already fully expanded and matured. The aboveground plant will also gradually stop growing, showing the phenomenon of physiological leaf drop. The growth of the tubers gradually ends, and the water slowly evaporates. At this time, we should harvest in a timely manner to prevent excessive growth from causing all the water in the tubers to be lost and affecting quality. When harvesting, pay attention to the force used, otherwise violent harvesting will cause mechanical wounds on the tubers, making them impossible to store.
