The field is full of straw, and the ridge is more than one meter long and overgrown with weeds. What if we don't let it burn?

Straw and ridge weeds in the field, if burned, can improve the field environment and inhibit the occurrence of pests and diseases. At the same time, the burnt plant ash is a good organic fertilizer, which can control the occurrence of soil-borne diseases. What a kill two birds with one stone! However, weeds more than one meter high on the ridge of the field do not advocate that straw should be returned to the field to prohibit burning now, nor do they say that smoke billows and pollutes the environment. It's just a small fire, the weather is dry and the autumn wind is rustling, and the fire spreads very quickly, which is difficult to control and prone to fire. Therefore, the ban on burning straw has its reasons. There is no explanation here, and it is not clear. Let me talk about our treatment. Please stop complaining. After the autumn harvest of rice, we are sowing wheat early, ploughing less and planting less, and returning all the straws to the fields. Now there is no need to leave straw after harvesting, all of them are pressed into short straw and fall into the field, leaving only rice piles and broken straw in the field. Sow directly in the field with good water content, and then let the wheat seeds fall on the soil with a shallow spin. The soil moisture is not good, so take the straw and rice piles under the soil by deep ploughing, and then sow them on it. I have already talked about the specific operation mode in the previous Q&A, and interested friends can consult. Sowed wheat should be fertilized after the seedlings are full, and then topdressing should be carried out according to the seedling situation.

For ridged grass, we basically ignore it at this time. Because we basically controlled some weeds in the early stage, some are not very stubborn weeds. At this time, they are basically dead, so there is no need to take care of them. When they grow again the next year, it is better to control them. For some stubborn weeds, although most of them will die in winter, in order to prevent them from coming out next year, they are found to be blue after harvesting, so it is necessary to use drugs in time to prevent them.

Weeds in rice ridges grow fast and are difficult to control, which is not conducive to rice growth and also affects the usual field care. Therefore, reasonable arrangements should be made according to the growth of weeds and working hours. As soon as I have time, I will go to places where there are many weeds to control.

By the middle stage of rice, the early prevention and control will be ineffective, and weeds will grow accordingly. Sometimes pesticides that are harmless to rice are chosen for prevention and control. During this period, there are often many things to do in the field, and the prevention and control of weeds will be ignored. Some ridges will be covered with weeds, which are also relatively high and resistant. Inactive herbicides should be used. In the later stage of rice field maintenance, glufosinate, glyphosate and dimethyl tetrachlorosodium salt were sprayed with water. Before spraying, the weeds should be spread flat on the ridge of the field, and then sprayed at a low position, which can not only prevent the liquid medicine from spraying on the rice plants, but also allow the weeds to receive drugs in all directions, so as to better play the role of prevention and control, and basically wait until the wheat harvest.

As for the field, there are more than one meter of weeds on the ridge, which are believed to be mostly Artemisia and thatch. At this time, it is basically in a yellow state, and there is no need to use drugs to prevent it, and drugs will not have an effect. You can let go completely. Under the action of rain, snow and cold wind in winter, you will basically fall to the ground and eventually rot slowly. If you are worried that the height of grass will affect the growth of crops, you can cut it off or trample it down manually. It's not bad to cut it mechanically and return it to the field. In addition, it is now advocated to return the straw from the field rice pile to the field, and accelerate the decomposition and dissolution by increasing the application of nitrogen fertilizer. We have been returning straw to the field for many years, and it has been so simple that there are no adverse reactions. According to crops and reasonable farming requirements, water and fertilizer management and pest control will not affect the yield. If rotation is not carried out, deep tillage can be carried out before winter, so that germs and diseases can be exposed on the soil surface to prevent overwintering, thus improving the soil environment. As for the weeds in the ridge, it is best to control them in the occurrence period and control their growth, so as to avoid the stubborn weeds with a wide variety and too many roots, which are difficult to control.
