How to treat the drug damage caused by metsulfuron to rice?
Remedial measures: after planting (throwing) seedlings in the herbicide field, the field inspection should be strengthened, and immediate measures should be taken to reduce the loss when herbicide damage occurs. 1 replanting (throwing) seedlings: after diagnosis, it was confirmed that the drug damage of the seedlings was serious, more than 80% of the seedlings were yellowed, and some of them withered, it was necessary to raise the seedlings to be replanted (thrown) immediately. Method of operation: first clear the field water, gently rake once and then discharge the turbid water, and then rake flat, transplant (throw seedlings). In recent years, the sowing and transplanting (throwing) seedling season is 7-15 days earlier than the traditional season. It is found that the drug damage is the most compensatory.

Trapping and killing effect of Jiaduo Frequency vibrating Insecticidal Lamp on Chilo suppressalis
Rice stem borer (Chilo suppressalis) is one of the important pests in rice production in Wuchang City. In recent years, with the change of rice varieties and the warming of climatic conditions in our city, the occurrence and harm of rice stem borer (Chilo suppressalis) is becoming more and more serious. According to the investigation this autumn, the average number of insects per mu of individual varieties of Wuchang reached more than 20, 000, and the highest number in key areas was as high as 60, 000, even more than 100000, which is rare in history, whether at home or abroad. In order to further control the damage of Chilo suppressalis, explore new ways to control Chilo suppressalis and reduce the pollution of insecticides to rice. Our city is in Wuchang this year.

Strengthen the Management of Seedling Field and cultivate strong Rice seedlings
1. The seedling bed tube for raising seedlings with flood and drought does not need to replenish water at the seedling stage, so as to improve the drought tolerance of the seedlings. At the same time, attention should be paid to watering the seedlings three times, that is, pouring enough "soil moisture" before sowing, pouring "uncovering film water" when the film is uncovered, and "rolling leaf water" during drought. We should properly control water in the first and second leaf stage to promote seed root rooting, pay attention to replenishing water to prevent dead seedlings in the second and third leaf stage, strictly control water after the third leaf stage, and cultivate physiologically strong seedlings by dry cultivation. In order to prevent too many Rain Water, dry farming and drought management can not be carried out, small arch shed or greenhouse can be strictly controlled.

Several Advanced Methods of Rice Seedling Planting
1. The improved intensive cultivation of 3 leaves to 4 leaves and 1 heart should be planted early, the field with good water source should be planted early, the field with poor water source can be slightly later, dry seedlings and wet seedlings are suitable, but they should be applied with sufficient base fertilizer, deep ploughing and leveling, strong seedlings should be selected as far as possible, and seedlings should be planted in shallow water; the row spacing and nest spacing are 1 foot 3 inches, and the spacing between three individual plants in each nest is triangular. This planting method has sparse density and sparse density, which reduces the competition between nutrients and sunlight to the greatest extent and is beneficial to the individual development of plants, thus increasing production by a large margin. It is the most advocated nowadays.

The technique of raising and strengthening Rice seedlings by Machine transplanting
With the improvement of the intensive level of rice production, mechanical transplanting has become an inevitable trend. One of the keys to the production of mechanically implanted rice is to raise strong seedlings. The following measures can be taken to raise and strengthen seedlings: 1. Apply seedling strengthening agent. Seedling strengthening agents are usually mixed with subsoil. First, mix a small amount of fine soil and seedling strengthening agent evenly, sprinkle it on the bottom of the seedling plate, and then add the subsoil. In order to avoid mixing and spreading unevenly because of too much subsoil, resulting in uneven distribution of seedling strengthening agents, resulting in dwarfing of seedlings in places with too many seedling strengthening agents, resulting in seedling shedding and affecting the quality of mechanical transplanting. two。 Cover the film.

Key points of cultivation in transplanting stage of mechanically implanted rice
First, make a good start and manage the seedling field well. 1. Look at the seedlings and fertilize them well. It is generally carried out 3-4 days before transplanting; the amount of fertilizer and application method should depend on the seedling color; the detached seedlings with faded leaves should be evenly sprayed or poured with urea 4-4.5 kg per mu to water 200 kg in the evening, and should be sprinkled once after application to prevent fertilizer-burning seedlings; the seedlings should be sprayed with urea 1-1.5 kg per mu and 60-70 kg water per mu The leaves are thick green and the leaves are covered with seedlings, do not apply fertilizer, water control measures should be taken to improve the quality of seedlings.

Several operating methods of Rice dry farming in Foreign countries
This new method has been invented by Tess Farm in New Orleans, USA. Specific operation method: on the wet no-tillage land, a small drill seeder (machine) is used to drill a hole in the soil with a diameter of about 3cm and a depth of 13-15cm. When drilling, two rice seeds are sown immediately. After sowing, the hole is covered with soil fertilizer, and the hole is filled with water, and the soil around the hole is only wet as straight. In general, no water can be given within 40 days after planting, so that the roots of rice mu grow deep and have strong roots, which can effectively
