Rice fungicide with low cost and high efficiency
20 dollars invested, 50 dollars returned. Would you do such a good thing? Last year, Shaoxing, Anji and other large grain farmers in rice planting after the use of "love seedlings", tasted such a sweet, rice production generally increased by about 10%. At present, it is the season of early rice application, and they are busy purchasing this new agent with high return rate for application to rice.
It is understood that 30% Aimiao EC is a new fungicide launched by Swiss Syngenta Crop Protection Company, which can control rice diseases and regulate rice growth. The pesticide has good control effect on rice sheath blight, rice kernel smut, rice false smut and other diseases. Last year, experiments on early rice and single-cropping rice in Shaoxing, Shangyu, Anji, Jiaxing and other places showed that after applying 30% Aimiao EC 15 ml per mu twice at the end of tillering and 3-7 days before the break of rice, not only effectively solved the disease problem at the heading stage, but also promoted the growth of rice, and obtained about 10% yield increase effect, and the grain was full and yellow and bright.
According to the input-output ratio calculation, one mu of rice with two "love seedlings", cost less than 20 yuan, according to the increase of 10%, output at least 50 yuan. Moreover, after using "Aimiao", the cost of medicine and labor for fungicides such as "Jinggangmycin" can be saved.

Effect of low temperature chilling injury on Rice and its Preventive measures
Rice chilling injury means that rice suffers from the influence of low temperature below the lowest critical temperature, which leads to the abnormal growth and development of rice and the reduction of rice yield. According to the different period of injury, it can be divided into delayed chilling injury, obstacle chilling injury and mixed chilling injury. 1. Types and characteristics of rice chilling injury 1. Delayed chilling injury rice in vegetative growth period, sometimes including reproductive growth period, suffers from lower temperature for a long time, weakens the physiological activity of rice plant, delays heading and flowering, and cannot be fully filled.

Which points should be paid attention to in the planting of late-planted rice in the whole field with water?
The overall requirement of late-planted rice in equal water field is to grab water and whole field to plant seedlings, increase nests, seedlings and ears. In case of precipitation or other water sources in the paddy fields with water-planted seedlings, measures such as water plugging, water diversion and pumping should be taken immediately to grab water and plant seedlings. Planting density should be increased in late planting fields. If the seedling age is 60 × 70 days, more than 13000 seedlings (8 × 6 inches) are planted in each mu of rice field, and two seedlings (2 grains) are planted in each litter; if the seedling age is more than 70 days, more than 15000 seedlings (8 × 5 inches) are planted in each mu of rice field, and the number of seedlings per mu reaches 150000 seedlings.
