This year's rice production reduction is mostly caused by climatic factors, but the selection of the varieties, the selection of fertilizer. Pay attention to every production link, scientific management, or a part of rice farmers' rice production is increased. That is to say, only by truly grasping every management link of rice production can it make its rice resistant under adverse environmental conditions. In order to obtain high yields under harsh weather conditions. Every aspect of rice cultivation must be prepared early, and there are problems. Every part of the work can be done in advance. So now that the rice is basically harvested, we should hurry and do the following things. Do the work in the coming year ahead of time to reduce the pressure of work in the coming year! First, it is difficult to prevent malignant weeds in autumn Some fields, fields, poolsides, pond stems, etc., have wintering rhizomes of malignant weeds. If there are green leaves or yellow-green, there is absorption capacity, and can be sprayed with glyphosate isopropylamine salt (Nongda) Control. After spraying for 3 days, if you can do the autumn turn, you can completely eliminate the overwintering root weeds. You can use 30 kg of water to water 2 bottles of Roundup spray. If there is wintering rhizome weeds in the seedbed, you can also use the “Nongda†spray to prevent the effect. Does not affect rice seedlings in the coming year. Second, the autumn seedbed soil When there is time to finish the harvest, I will immediately prepare the seedbed soil, prepare the soil for the autumn, and sift the soil for the autumn, which will win a lot of time for the spring of next year. Dry this autumn, the soil is relatively dry, better sieve. Preventing snow in winter and warming up in the spring, causing difficulty in obtaining soil in the spring of next year, and difficulty in screening soil, affecting the time of seedlings in the coming year. The seedbed soil must be selected from the salt-free alkali, and there is no herbicide residue, and the soil with high organic matter content is used as the seedbed soil. Third, try to sit in bed in autumn Making autumn beds in autumn can not only win time for spring seedlings in the coming year, but also improve the quality of seedbeds. In autumn, rice seedlings can be placed in bed. After winter freezing, the looseness, permeability and water permeability of the soil can be improved. , heating up quickly. In order to raise seedlings early and develop high-quality and strong seedlings, it has laid a solid foundation. If the seedbed is soy, the leaves and roots are removed, and the flattening can be done. If the seedbed has more wintering rhizome weeds, it is best to turn the ground in autumn, make up the autumn, and make the bed in autumn. It is necessary to clean the wintering rhizome and root stalks, leveling and squeezing, and filling the pressure to make the bed imaginary. It will help to set the plate and heat up in the spring of next year. If the seedbed is relatively low, it is best to dig the drainage ditch on both sides of the greenhouse. It can reduce the water content of the seedbed and increase the temperature of the seedbed. It is best to place the bed sand in the greenhouse where the soil is not good, and the seedling effect is very good. Fourth, timely fall to the ground Conditional plots, if the surrounding has been harvested, first select the windless weather, look at the inner ring of the field, burn the circle, then burn the straw inside, to prevent running fire. The best time to turn the ground is before the freezing, and it can be turned. When the soil is wet, it will freeze when it is turned over, and the soil will be loose in spring. Generally, in late October, the effect of turning over the ground is best in the first ten days of November, and it is too early to turn into dry clods. It is better to freeze the clods on the frozen clods. It is necessary to master the timing of turning over the ground, and the soil in the autumn turnover is well matured, the seedlings are fast, and the pests and diseases are less, which is more than the spring turning over and not turning over the ground.
