Due to the special landforms in the mountains, it is easy to form “mountain windsâ€. Therefore, it is necessary to adjust measures to local conditions and to reserve the direction of the corn for the natural wind direction based on the topography and topography of the blocks, and it is advisable to set a joint reserve.
1. According to the wind direction, reserve a high-level reservation line.
2. Increase fertilizer input and increase fertilizer levels. In order to meet the requirements of high density, it is necessary to increase fertilizer input and change the improper fertilization method. The requirements for applying base fertilizer per acre are: 1000-1500 kg of high-quality farmyard fertilizer, 10 kg of urea, 15 kg of phosphate fertilizer, and 10 kg of potash fertilizer. Fertilization method: The phosphorus and potash fertilizers are mixed into farmyard manure, combined with site preparation withdrawal and turning into corn reserve soil.
3. Reasonably adjust the density structure. In order to solve the problem of unreasonable corn planting density, 4000 plants per mu were promoted. Based on this, the reserved belt type can be adjusted to increase the row spacing and spacing as much as possible.
4. Select the best sowing date. Because of the low temperature in the high mountains and the strong seasonality, early sowing is beneficial to early fertility and prolong the growth period, and it is possible to increase seed-setting rate, increase grain weight and yield.
5. In the middle and later stages, the film was removed and the roots were removed. The high-temperature film removal in the middle and later stages is conducive to the natural adjustment of soil air, temperature, and humidity, which facilitates the management of the high water and fertilizer requirements in the middle and later stages of corn growth. The soil is cultivated in time to achieve deeper root absorption and meet the needs of water and fertilizer on the ground. Enhance plant function and resistance.
6. Topdressing anti-reverse fertilizer. Grasp scientific, timely, reasonable, uniform force-fed principle, and according to the basic fertilizer, seedling situation, growth period to determine a reasonable amount of top dressing and topdressing period. Generally, the amount of topdressing fertilizer can be controlled at a rate of 40 kilograms per acre of nitrogen, which can be applied at each birth period. The principle of “suitable in appropriate amount and timely recovery†can be mastered so as to achieve favorable results for harmlessness and stamina. The corn's absorption function, reproductive function, and anti-inversion function are continuously enhanced.
