1. Select sandy loam soil or sandy land with deep plowed layer, loose texture and medium fertility.
2. Prepare the induction tube. Each plant is equipped with a bamboo tube or a plastic tube with a length of 1 meter and a radius of 8-10 cm. When the plant is inducted, the tube is filled with fine sand and the slope is placed at 15-20. The potato seedling is planted at the high end of the catheter at a distance of 10 cm.
3, timely planting, rational close planting: grasp in the germination in mid-to-late, late March, mid-planting. Even with a ditch with a row spacing of 1. 40.35 meters, 1300 acres of planting, acres of 150-200 kilograms of sufficient planting potatoes.
4, under the foot base fertilizer, apply fertilizer early. 20-30 lbs. per mu of manure and waste fertilizer, applied to the gap between the induction pipe, the long period of quasi-yama, high yield, need more fertilizer, the whole growth period to top dressing 5-6 times, with compound fertilizer Lord, mixing water or casting.
5. Strengthen field management and timely cultivating and weed control: In order to prevent weeds, weed herbicide (such as Kyoto) can be used to prevent weeds immediately after planting, and we must pay attention to drainage and prevent waterlogging in the early stage; potato tube elongation and enlargement period ( July and August) In case of drought, cover the surface with straw, waterproof and evaporate.
new high-performance sensors can effectively detect smouldering fires It can detect all kinds of indoor smoke. When the indoor smoke volume reaches the alarm concentration, the detector will alarm, the red indicator light will be on, and the buzzer will beep, so as to prompt the user to timely check the causes of the leakage accident and eliminate potential safety hazards.
