Abstract
The invention discloses a cotton aphid control method. The method is achieved by multiplying natural enemies in the field through sorghum aphid breeding on sorghum and by planting sorghum on the edge of a cotton belt. The ratio of the number of rows of the cotton belt to the number of rows of a sorghum belt is 6-10:1. A row gap of the cotton belt is 30-50 cm, and a row gap of the sorghum is 40-50 cm. The number of rows of the sorghum in the sorghum belt is 1-4, and the sorghum is one or two of sweet sorghum or glutinous sorghum. The adopted sorghum is annual crop and is applicable to diversified cropland cotton regions in Yangtze river and Yellow river basins in our country. Host specificity of the sorghum aphid is high so that the sorghum aphid can not jeopardize local main crops such as cotton and corn. Planting of sorghum is relatively simple, the sorghum is strong in adaptability to the field, and special management is not required. By breeding the sorghum aphid on the sorghum belt, the density of the natural enemies in the field is increased, and an effect of controlling cotton aphid damage to cotton is achieved.
Description
Technical field
The invention belongs to agricultural technology field, be specifically related to the prevention and controls of a kind of cotten aphid.
Background technology
China is Cotton Production state maximum in the world, and be also maximum cotton country of consumption, therefore Cotton Production is significant for the economic development of China.Along with transgenic Bt cotton is in the large scale application of China, the sucking insects such as cotten aphid become the primary pest in cotton field, serious to Cotton Production harm.At present, the control of cotten aphid depends on chemical insecticide, and chemical control often brings environmental pollution, insect produces the series of problems such as resistance, pest resurgence.Along with the continuous rise of pollution-free industry, method based on chemical control is replaced by make full use of the ecological control method that natural enemy Pest control efficacy is core gradually, set up in early days for natural enemy population by the cropping pattern of adjustment crop and increase exactly and food and suitable habitat are provided, increase natural enemy to the control action of target pest.
Utilize clover to be with in the method controlling cotten aphid in prior art, clover is perennial plant, is only applicable to acreage under cotton large, the Xinjiang cotton that position is fixing; And clover is cotton primary pest--the host of fleahopper, although cotton field band Planting Medicago sativa can control cotten aphid, also can increase the harm of fleahopper silk worm.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, theoretical based on ecology regulation and control, provide the prevention and controls of a kind of cotten aphid, by the sorghum aphid that Chinese sorghum grows, increase the density of field natural enemy ladybug, minute pirate bugs, Chrysopa, thus reach the effect of cotten aphid on control cotton.
Concrete technical scheme of the present invention is:
A prevention and controls for cotten aphid, the natural enemy of being bred field by the sorghum aphid on Chinese sorghum is realized.
Bring realization more specifically by the edge planting Chinese sorghum be with in cotton, the line number that the line number of described cotton band and Chinese sorghum are with is than being 6-10:1, and the line space that described cotton is with is 30-50cm, and the line space of described Chinese sorghum is 40-50cm.
If cotton band line number is too low, do not reach the plantation output of cotton, if Chinese sorghum band line number is too low, the effect of prevention and control of aphides can not be played again preferably.Chinese sorghum can grow a large amount of sorghum aphid, for the natural enemy ladybug of cotten aphid, minute pirate bugs, Chrysopa provide early stage food source (sorghum aphid) and habitat, by the cotten aphid that the growth differences of Chinese sorghum and cotton makes natural enemy ladybug, minute pirate bugs, Chrysopa prey on field, thus reach the object of prevention and control of aphides.August, cotton field volt aphid occurrence in peak period, not having Chinese sorghum to be with the quantity of the cotten aphid in contrast cotton field to be cotton is 8 times in the cotton field of 6:1,8:1 and 10:1 with the line number ratio of Chinese sorghum, plants population quantity and harm that Chinese sorghum band effectively can control cotten aphid in cotton field around cotton field.
The line number that the line number of described cotton band and Chinese sorghum are with is than being 8:1, under such ratio, Chinese sorghum band is planted around cotton field, the sorghum aphid grown is brought by Chinese sorghum, increase the density of field natural enemy ladybug, minute pirate bugs, Chrysopa, the effect of prevention and control of aphides reaches best, effective population quantity and the harm controlling cotten aphid in cotton field.
In described Chinese sorghum band, the line number of Chinese sorghum is that 1-4 is capable.This line number requires to be convenient to natural enemy ladybug on Chinese sorghum, minute pirate bugs, Chrysopa are spread on cotton, if Chinese sorghum line number is too much, the natural enemy range of scatter on it is limited, so that do not reach good control efficiency to the cotten aphid on cotton.
Described Chinese sorghum is one or both of sugar grass or glutinous sorghum, these two kinds of sorghum varieties are high sense aphid kinds, the generation of very suitable sorghum aphid, inventor is filtered out from more than 200 sorghum varieties by a large amount of experiments can the sorghum variety of amount reproduction sorghum aphid, by a large amount of sorghum aphids that Chinese sorghum grows, increase the density of field natural enemy ladybug, minute pirate bugs, Chrysopa, and then reach the object of aphid on control cotton; Because the host specificity of sorghum aphid is very high, so other crops can not be endangered; Cotton is advisable than at 8:1 with the line number of Chinese sorghum, and the too little sown areas of cotton that cause of ratio are less, do not reach yield target, and ratio does not then reach too greatly the effect of natural enemy prevention and control of aphides.
The Chinese sorghum adopted in the method for the invention is annual crop, is applicable to cotton region, diversified farmland, China's Yangtze and Yellow rivers basin; The host specificity of sorghum aphid is very high, so can not endanger cotton and corn etc. as landlord to plant crop; The plantation of Chinese sorghum is relatively simple, adaptable to field, does not need special management.The present invention brings the growth of sorghum aphid by Chinese sorghum, increases the density of field natural enemy ladybug, minute pirate bugs, Chrysopa, thus reaches the effect of cotten aphid harm on control cotton.
Accompanying drawing explanation
Fig. 1 is the plantation schematic diagram of the method for the invention;
Fig. 2 is under cotton and Chinese sorghum different rows ratio, cotten aphid occurrence in peak period quantity figure in cotton field;
