The fertilizer and pesticide used in the blank example were the same as those used in example 4.
TABLE 1
Referring to table 1, comparing the blank examples and examples 1 to 4, it can be seen that when the seed soaking of the netherlands seed of example 4 is additionally performed, the probability of wilt and brown spot of the bud-based box of the netherlands seed can be obviously reduced, thereby improving the yield of the netherlands seed, and enabling the yield of the netherlands seed after cotton interplanting to be closer to the yield before interplanting;
comparing example 4 with example 5, it can be seen that when the sodium nitrate content in the second disinfectant is increased, the seed soaking effect is reduced, and the incidence of the netherlands is slightly increased;
comparative example 4 and comparative examples 1 to 3, it can be seen that when different fertilizers are selected, different effects are produced, and the fertilizer selected in example 4 can achieve the best effects;
it should be noted that, for the control of the netherlands bean diseases, a fertilization mode and an application mode can be adopted, and compared with the example 4 and the comparative example 4, the yield of the comparative example 4 is obviously lower than that of the example 4, and the application in the step (5) can improve the control effect by adding phoxim emulsifiable concentrate;
comparative example 4 and comparative examples 5 and 6, it can be seen that the control effect is significantly weaker than the combined effect of kresoxim-methyl and sodium nitrate when the second sterilizing liquid adopts a single hydrogen peroxide solution or kresoxim-methyl.
