Apply base fertilizer. Many people planted cassava into the mountains and dry lands, did not use basal fertilizer, and they grew long, so the yield was very low. In order to improve the planting efficiency of cassava, it should first turn a good place, 1 meter spacing, make a good point, apply enough chicken manure, grass ash, garbage mud and other mixed fertilizers, a big bowl per hole, lay a good foundation for emergence and long potatoes.
Choose good breeds. Good planting good seedlings, high and low yield, good seed is the key. The improved varieties of cassava include Nanzhi 188, Zhongshan cassava, etc. If the stem stems and branch stems are used as seeds and the potato is small and small, one-metre root stems should be used for disease-free, non-injury and dense-seedling species. Take 20 centimeters for a period, use a knife to cut out the oblique mouth at the bottom end, 8 cm above the oblique mouth, cut the skin to the xylem, strip out a 2 cm skin length, a gap of 3/4 of the stem circumference, leaving 1/4 of the skin Output water and nutrients, up to 14 cm, still cut a notch, put the stem horizontally in the base fat hole, cover 3-5 cm of soil. This new planting method is drought-tolerant and wind-resisting, and it is not easy to overturn roots, and multi-layered sweet potato makes it easy for the potato to grow thick and long.
Deworming rodents. When cassava was first emerged, tigers like to steal food. A tiger can eat a seedling overnight, which is very harmful. The ground tiger burrowed into the hole and came out to eat cassava seedlings at night, drilled back into the hole before dawn, and sealed the hole with new mud. Therefore, artificially digging 10-20 cm can be caught and can be used to feed chickens. In the long potato period, rats will steal potatoes and take rodent control measures.
Weeding and fertilizing. When the seedlings grow to 20 centimeters or so, only one of the most robust seedlings can be set aside. Other seedlings can be picked and fed. At the same time, it is necessary to carry out planing and loosing soil, and the grass will be hit by mud and covered near the root. A spoonful of urea per plant was used to cover the soil and promote seedling growth. When the seedlings grow to 1 m, we will do the second weeding and loosening the soil, but do not cut the fries. Each plant will use one spoonful of compound fertilizer, which will grow both long and long. The long potato stage, generally encountered in the dry season, due to hard ground, difficult to grow potatoes, is bound to reduce production, so it is best to water once a week to keep the soil wet, conducive to the growth of potatoes.
Keep good stems. If cassava is harvested too early, there will be less starch, more water, and a lower rate of drying. Should be selected in mid-November sunny harvest potatoes. Take a thick, disease-free, dense-stemmed main stem of 1 meter, or the main stem below the split, and dig holes to store and seal the hole. You can also dig deep pits on the slopes, put the stems down, cover with 10 cm of soil, and cover with straw to prevent frost and snow from freezing, and make full preparations for the spring season next year.
