Problems solved by technology

[0003] At present, the main control measures adopted mainly include cultivating resistant varieties and spraying chemical pesticides, but breeding new varieties is time-consuming and the disease resistance is weakened or lost with the variation of pathogenic bacteria
Although there are dozens of pesticides in the prevention and treatment of cotton verticillium wilt, huge manpower and material resources are invested every year, but the effect is not very obvious, and some pesticides do not even have any effect, so that cotton farmers invest a lot in the prevention and treatment of cotton verticillium wilt, and the results are effective. In addition, chemical pesticides are likely to cause pesticide residues and damage the ecological balance of the soil

Embodiment 1

[0086] In 2017, it was applied to 110 mu of drip irrigation cotton in No. 12 land of the third round of the Xinjiang Academy of Agricultural Sciences Test Site. Different growth periods, different water-soluble fertilizers were drip-irrigated with water, the dosage of water-soluble fertilizers, the time of drip application, the frequency of use and The amount of dripping water is shown in Table 1.

[0087] Table 1

[0088]

[0089] Application results: the final cotton yield is 423 kg / mu, which is 5.26% higher than that of the control field, and the disease prevention effect is increased by 43.8%.

Embodiment 2

[0091] In 2017, it was applied to 190 mu of drip irrigation cotton in the No. 8 land of the 2nd Company of the 125th Regiment of the 7th Division of the Kuitun Corps. In different growth periods, different water-soluble composite fertilizers were drip-irrigated with water, the dosage, drip application time, and application of water-soluble composite fertilizers. The number of times and the amount of dripping water are shown in Table 2.

[0092] Table 2

[0093]

[0094] Application results: the final cotton yield is 415 kg / mu, which is 12.16% higher than that of the control field, and the disease prevention effect is increased by 55.0%.

Embodiment 3

[0096] In 2017, it was applied to 210 mu of drip irrigation cotton in No. 16, 8th Company, 129th Regiment, 7th Division, 129th Regiment of the Kuitun Corps. In different growth periods, different water-soluble composite fertilizers were drip-irrigated with water, the dosage, drip application time, and application of water-soluble composite fertilizers The number of times and the amount of dripping water are shown in Table 3.

[0097] table 3

[0098]

[0099] Application results: the final cotton yield is 405 kg / mu, which is 9.5% higher than that of the control field, and the disease prevention effect is increased by 47.6%.

[0100] Explanation: all mentioned contrast field among the above-mentioned embodiment 1, embodiment 2 and embodiment 3, this contrast field refers to only applying conventional macroelement water-soluble fertilizer (urea, No. 1 fertilizer and No. 2 fertilizer).

[0101] The control method of the present invention has been demonstrated in the key cotto...

Abstract

The invention relates to a method for preventing and controlling cotton verticillium wilt. The method comprises the following step: dripping a first water-soluble compound fertilizer, a second water-soluble compound fertilizer, a third water-soluble compound fertilizer and a fourth water-soluble compound fertilizer into cotton root soil together with water at the seeding stage, bud stage, flowering stage and boll stage of cotton, wherein the first water-soluble compound fertilizer, the second water-soluble compound fertilizer and the third water-soluble compound fertilizer all contain a bio-organic micro fertilizer; the micro fertilizer is prepared from a water-soluble organic matter, fulvic acid, medium trace elements and a microbial preparation. The water-soluble compound fertilizers aredripped into the cotton root soil by an integral water-fertilizer irrigating technology, and various components play a synergistic effect, so that significant growth of cotton is promoted, and the pathogenic bacteria resistance of cotton is improved. Meanwhile, introduced beneficial microbial flora can breed rapidly in order to block and isolate the contact between the pathogenic bacteria and cotton root, so that the infection incidence is lowered, and the effect of preventing and controlling cotton verticillium wilt is achieved.

Description

technical field [0001] The invention relates to a method for preventing and controlling crop diseases, in particular to a method for preventing and controlling cotton verticillium wilt. Background technique [0002] Cotton verticillium wilt is a cancer of cotton, which can reduce cotton production by 40%-60%, and severely diseased fields can cause crop failure. Verticillium wilt of cotton is a disease caused by pathogens in the soil attacking crops from the roots of cotton when conditions are favorable. In recent years, cotton verticillium wilt has become more and more serious in Xinjiang. The reason is that cotton has been planted repeatedly for many years, and the stalks of diseased cotton plants are returned to the field, which makes the number of pathogenic bacteria in the soil continue to accumulate and expand. [0003] At present, the main control measures adopted mainly include cultivating resistant varieties and spraying chemical pesticides, but breeding new varieti...
