First, 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 is necessary to first turn the land well, with a spacing of 1 m, to lay a good point, and to apply a mixture of chicken manure, vegetation ash, garbage sludge, etc. A large bowl per hole will lay the foundation for emergence and long potato.
Second, choose a good seed
Good planting good seedlings, high and low yield, good seed is the key. The varieties of cassava include Nanzhi 188, Zhongshan cassava, etc. If the stem stems and branches are used as seeds, the number of potatoes is small and small. Use a disease-free, non-injury, dense-stemmed root stem 1 meter for the 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 nourishment, up to 14 cm, and then cut a notch, put the stem horizontally in the basal fat hole, cover the soil of 3- 5 cm. 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.
Three, pest control rat
When the cassava has just emerged, the soil tiger prefers 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. It was drilled back into the hole before dawn and used new mud to seal the hole. So 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.
Fourth, weeding and fertilizing
When the seedlings grow to 20 centimeters or so, only one of the most robust seedlings can be set aside, and other seedlings can be picked and fed. At the same time, we also need to remove the plan and loosen the soil and put the grass to cover the mud and cover it 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 loosing soil, but do not cut the fries. Each plant will use one spoonful of compound fertilizer, which will grow both long and long. In the long potato stage, generally encountered in the dry season, because of the hard ground, the potato is difficult to grow, and it is bound to reduce the output. At this time, it is best to pour water once a week to keep the soil wet and loose, which will benefit the growth of potatoes.
Five, keep a good variety of 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 a main stem below the split, and dig holes to store and seal wells in the north-facing hill. 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.
