Description
Technical Field
The invention belongs to the technical field of prevention and treatment of diseases of rice in saline-alkali soil, and particularly relates to a method for preventing and treating rice stripe disease in saline-alkali soil.
Background
The rice stripe disease is a virus disease on rice, and once the rice is infected with the virus disease, the rice is difficult to control, so the rice stripe disease is called as rice cancer by farmers. The occurrence of the rice stripe disease is closely related to the quantity and the toxicity rate of the pests with the green planthopper. The laodelphax striatellus is a virus transfer medium of rice stripe disease, and adult and nymphs of the laodelphax striatellus can stab host juice of rice and the like to cause yellow leaves, so that the laodelphax striatellus is directly harmful to the rice and can also spread the stripe disease. The small brown planthopper cannot show symptoms in a short period after being spread and transmitted with toxin, so that the disease symptoms cannot be seen, the prevention and control time is easy to miss, and the small brown planthopper has multiple generations, migration and diffusion, generation overlapping, long toxin transmission time, high prevention and control difficulty and poor dispersion prevention and control effect.
The virus is only infected by vector insects, and other ways do not transmit diseases. The mediator insects are mainly Laodelphax striatellus, and can be infected by ovum for a lifetime once the insects obtain the poison, the shortest virus absorption time is 10min, and the circulation period is 4-23d, generally 10-15 d. The virus infects various plants of Gramineae such as rice, wheat, barley, oat, corn, millet, alopecurus, green bristlegrass and the like. However, except for rice, other hosts have little effect on the infection cycle. The virus overwinter in the body with the poisonous Laodelphax striatellus becomes a main initial infection source. Nymphs overwintering in large and wheat fields are bred in the original wheat field after emergence, then are migrated to the seedling field of early rice or the field to transmit toxicity as harm and breed, the nymphs are migrated to late rice as harm after harvesting the early rice, and are migrated back to winter wheat for overwintering after harvesting the late rice. The rice is susceptible to diseases from the seedling stage to the mulberry stage, the leaf age is long and the submerged period is long, and the resistance is gradually enhanced along with the growth of the plants. The occurrence of the stripe disease is directly related to the occurrence amount and the pest carrying rate of the laodelphax striatellus. In spring, the temperature is too high, rainfall is less, and insect population is frequently encountered and seriously ill. The disease is serious in the rice and wheat double cropping area, and the disease is slight in the barley and double cropping rice area. Although the sogatella furcifera can also transmit the rice stripe virus in nature, the effect is not great.
The main factors influencing the severe occurrence of the rice stripe disease are as follows: firstly, the farming system is changed, and the double cropping of rice and wheat is beneficial to the population and pathogen circulation of the laodelphax striatellus; secondly, the climate gradually becomes warm, the warm winter is beneficial to safe overwintering of the laodelphax striatellus, the overwintering base number is large, the population density of the first generation adults is high, and in addition, the temperature in early spring is high, the laodelphax striatellus grows fast, the time for the adults to move into the seedling bed is short, the number of days for transmitting the poison is prolonged, and the number of days for transmitting the poison is increased; the disease severity is seen from the cultivation mode that the seedlings are transplanted in fields with too early sowing, the color of the seedlings is light green, the transplanting density of the seedlings is too high, and diseases develop in direct-sowing rice fields in idle winter fields are serious, which is mainly consistent with the adult Laodelphax striatellus and the seedling stage of the seedlings, and the feeding habit of the Laodelphax striatellus likes the light green population with rich nitrogen and nutrition of the rice, so that the virus transfer quantity of the Laodelphax striatellus in the fields is increased, and the diseases are aggravated.
For the prevention and control of rice stripe disease, the general methods include chemical prevention and control, agricultural prevention and control and the like, wherein the chemical prevention and control comprises the following steps: the pest control and disease prevention are targeted in the disease circulation area. The early rice seedling field has 18 adult insects per square meter on average, the late rice seedling field has 5 adult insects, and the application of pesticide should be carried out for preventing and treating the adult insects in the early stage of the field and more than 1 adult insects in each cluster on average. The medicament can be selected from: 750 liters of water is sprayed with 375-450 grams of buprofezin wettable powder with the concentration of 25 percent per hectare, or 3750 grams of cicada powder with the concentration of 10 percent per hectare, or 2250 grams of metolcarb wettable powder with the concentration of 25 percent per hectare. Agricultural control: firstly, resistant varieties are selected, and secondly, natural enemies are protected and utilized.
