This year's situation is not much different from last year, and Sunflower Land still faces drought problems. The phenomenon of drought after sunflowers has led to two adverse effects: one is the decline in the rate of rotten plates, and the other is that premature maturity of sunflowers leads to premature aging. The eldest brother joked: "Give enough water and fertilizer, the sunflowers will naturally ripen, which is the end of life; If there is not enough fertilizer, sunflowers will mature prematurely and age prematurely, which is 'drought death'. "Predictably, production will be affected, that's for sure. In dry fields, the waterfield should be hydrated as much as possible and the required fertilizer should be provided at the bottom. If there are repeated droughts, it is necessary to water several times and in small amounts, while adding the right amount of nutrients for management, so as to avoid yield losses due to improper human management. Big brother, you have brown spot in your field. If this is not controlled, the middle of the leaf is damaged, resulting in nutrient dispersion and affecting yield. In such cases, the disease should be treated before nutrition is provided. Water is essential, and the reduction in production due to lack of water is obvious. In drylands, when nesting with a water wheel, too many nests can cause leaf disease and waste nutrients. Therefore, the disease should be treated before nutrition. Both varieties are the same, but those who use foliar fertilizer in the early days have successfully taken root. The other side did not use foliar fertilizer, and osmanthus grew better than it in the early days, but due to lack of water, the root system was not developed, and it could only grow on the surface, resulting in drought death. Now, their leaves are all withered and very visible, like water droplets. The lesson of this year is that land is not about much, but about being fine. As long as it is yellow, it is yours, and as long as it is black, it is using foliar fertilizer.
