First, the dominant species The selection of good varieties should be selected from high-yielding, high-quality, broad-adapted and multi-resistance varieties of hybrid maize, Zhenxing 508 and Yunrui 88. Second, the main push technology 1. Select the plot. Select convenient transportation, the masses are actively growing high grain, strong sense of science and technology and good soil properties for demonstration plots. 2. Select a new hybrid corn variety with high yield, good quality, wide adaptability, and multi-resistance as the dominant species in the demonstration area. 3. Fine soil preparation, early sowing in time, film covering. After the Xiaochun crop is harvested, it can be planted without tillage. It can't be cultivated in a timely manner. It can be ground-covered, not compacted, and it can be applied to the imaginary condition. It ensures good sowing, ensuring that the seeds can be sowed before May 10th, until the corn emerges. , combined with cultivator weeding and fertilization after the cover film. 4. Properly densely planted to optimize the community structure. In the demonstration area, 2 kilograms of corn seeds will be sowed in acres and 4000--4,500 strains will be planted in acres. In the past, the seedlings were replanted several times, except for young seedlings and strong seedlings. Use (80+50) 45 cm wide and narrow rows to plant two plants, optimize the structure of the population, and lay a good foundation for high yields. 5. Scientific fertilization. Use good soil testing and formula fertilization promotion. Mu Shi 1500-2000 kg farmyard fertilizer, corn special compound fertilizer 40 kg, 50 kg of phosphate fertilizer as the base fertilizer. The corn grows to the 4- to 5-leaf stage in combination with the tillage and rushing grass to raise the seedling fertilizer, and the Mushi urea 10--15 kilograms; 8-10 leaves (big bell-mouth period) to carry out the planting of the bar fertilizer, the Mushi urea 25--30 kg. 6. Strengthen field management. The first is to start early, so that 3 leaf seedlings, 5 leaves Dingmiao, 6 to 9 to strengthen the management of the cultivator, 10 leaf water and fertilizer attack. The second is to prevent pests and weeds in a timely manner, adhere to the "prevention-based, comprehensive prevention and control" plant protection policy, to achieve "safe, effective, and economical" control purposes. The main prevention and control of field weeds, corn borer, corn borer and other pests, large-scale disease, gray spot disease and other diseases. Integrated control of pests and diseases to reach 100%, in addition to the area accounting for more than 90%. 7. timely harvest. Harvest to achieve "nine yellow and ten income," promptly stripped after the closing of the loquat leaves, using 4--6 ear knot hanging drying, to avoid the harvest due to the timely removal of loquat leaves caused by rotten rotten bad, so that high yield bumper harvest. 40m Laser Distance Meter is a functional and advanced measuring tools, no need climbing up and down, which is the engineers' best friends.
