High-yielding Cultivation Techniques of Maize
(1) Select high-yield and disease-resistant hybrid maize varieties to ensure that the target yield index is achieved. The main varieties used are Haishu No. 1, Haidai 14, Beiyu No. 2, Beiyu 20, Yayu 78, and Yayu 889.
(2) Grasp the season and sow at the right time. According to the actual situation of the creation of the area, it is required that the sowing be completed on April 20 to May 10. And farmers are required to raise sufficient seedlings to check seedlings for deficiency.
(3) Areas above 1700 meters above sea level shall be vigorously promoted to cover corn mulching.
(4) Reasonable fertilization, application of base fertilizer, N, p, k in combination with application. Mu application of 1500 kg of organic fertilizer, 50 kg of general calcium fertilizer, 15 kg of urea, 10 kg of potassium sulfate, 1 kg of zinc sulfate as the base fertilizer. The first time cultivating topdressing Mushi urea (miaofei) 10 kg, the second cultivator topdressing Mushi urea (panicle) 15 kg, the third top dressing according to the growing situation of mu application of urea (grain fertilizer) 5 kg.
(5) Standardized planting and reasonable close planting. The use of wide and narrow rows of dual-line drilling, large spacing of 3 - 3.2 feet, a small row spacing of 1.2 feet, plant spacing of 0.8 - 0.9 feet, acres of density guaranteed in 4000 - 4500 strains.
(6) Do a good job of drought relief and drainage measures. When there is a drought, the areas with conditions will be able to divert water from drought and protect the seedlings, ensure that the corn grows robustly, and prevent the lack of ponds caused by the lack of water causing seedlings to die. At the same time, it is necessary to strengthen the drainage of the plots to prevent flooding and prevent the normal growth of corn due to poor drainage.
(7) Strengthen integrated pest management. Adhere to the principle of “prevention as the mainstay and comprehensive prevention and control†and do a good job in forecasting and controlling the pests and diseases, and in addition to guiding and supervising farmers to carry out pest control work, aim at the characteristics of corn, small-spot disease and gray-spot disease. Combine with the plant protection department to grasp the rule of general defense 1-2 times.
Short range distance sensors from JRT combine highly precise measurement results with quick and reliable response. Short distance sensor module use single-transmit and single-receive measurement technology and can be used to measure a distance or monitor the slow moving objects. For the laser pointer distance measure, also called optical range sensor, can measure legth, width, depth. Laser rangefinder transducer with rxtx has been widely used to industries.
