The latest field management of rice in summer

After the shelling of rice, we must eat rice every day. As the staple food of southerners, rice is almost the food crop that must be planted in the whole south. Growing rice must be very familiar to everyone. Summer is the most critical period for rice growth. Managing the growth of rice in summer is an important work to ensure high yield and high quality of rice. So how to manage the fields in summer? Let's take a look at it.

1. Moisture

In summer, especially in July, the water in the field should not be too deep in the first ten days, and the water layer should be controlled around 4cm. This can not only ensure the breathing of the root, but also discharge harmful gases that affect the growth of rice, so that the root growth is more robust, the depth of downward extension is deeper, and the absorption of nutrients is more adequate. In mid-July, it is necessary to prevent the temperature from being too low and cause chilling damage to rice. If the temperature reaches 15 degrees, the water layer should be deepened to keep warm. It can reduce the probability of no meat grain and white ear, appropriately increase the surface temperature, and promote the nutrition absorption of rice.

2. Panicle fertilizer

After entering summer, the topdressing of panicle fertilizer is very important. Proper application of panicle fertilizer to rice can effectively increase the number of panicle flowers and prevent premature senescence of rice. It can also effectively improve the seed setting rate in the later stage and increase the weight of rice grains. The specific fertilization time depends on the growth progress of rice, which is usually applied when the second leaf of the seedling grows out of 1ap2. Panicle fertilizer can be used with potassium fertilizer combined with a small amount of nitrogen fertilizer. Panicle fertilizer is usually applied twice, the first time in the heading period, and then the second time in the full heading time.

3. Weeding

Summer is not only a time of rapid growth of rice, but also a season of weeds, weeds will compete with rice for nutrients and water, and too much will block the light in the field, which has a great impact on the normal growth of rice. Therefore, we should inspect the rice fields regularly, remove the weeds in the ridges and fields in time, pay attention to the use of herbicides to prevent rice from being harmed, and be careful not to hurt the roots of rice if it is artificial weeding. Reduce the breeding of bacteria and provide a good growth environment for rice.

4. Disease prevention

Rice gradually enters the booting stage in summer, which is the most vulnerable stage in the whole growth process of rice, but summer is the season with high incidence of various diseases and insect pests. The main diseases are rice blast, brown spot and so on, mainly based on prevention, control agents can not be used alone, according to the specific diseases and the corresponding chemical control. The main pests are negative mud insects and rice planthoppers, which will eat the leaves of rice in time and affect the photosynthesis of rice. To reduce the accumulation of nutrients in rice, Awei and other chemicals can be used for control.

The above is the management method of rice in summer, the summer management of rice is very important, because it is directly related to the yield and grain weight in the later stage. It is mainly the prevention and control of diseases and insect pests in the first place, and the prevention and control of diseases and insect pests must be in place, otherwise it will lead to a fall short of success and all the work of a year will be wasted.
