Comparative example 1
The comparison example is a common cotton planting method in the prior art, generally adopts a continuous cropping mode, a planting mode of sowing or transplanting cotton after winter cropping in the same cotton field, ploughing and preparing soil: due to continuous cropping, the cotton field is deep ploughed once before winter crops are planted after cotton harvesting, no land is ploughed when cotton is planted in production, and cotton is directly planted after winter crops are harvested. The detailed procedure of this comparative example is as follows:
sowing in the first ten days of the month T1 and 4, selecting excellent varieties popularized in production, and sunning for 3-4 days before sowing 15 days; the seedbed management is well done, the dead seedlings are prevented, the seedlings are acclimated in time, and the seedlings are transplanted in time;
transplanting in late middle of 5 months at T2 with field density of 1200-2000 plants, and applying enough basic fertilizer (including nitrogen fertilizer of 6-8 kg/mu and P)2O5Fertilizer 3.8-5.4 kg/mu, K2O fertilizer 7.68-12 kg/mu), soil fertility, light seedling fertilizer application, stable bud fertilizer application, heavy flower bell fertilizer application, peach fertilizer application, and K is added in total25.12-8kg of O fertilizer per mu and P2O53.8-5.4 kg/mu of fertilizer is used for ensuring the requirement of N, P, K in the whole growth period of cotton; t3, pruning: removing leaf branches, topping cores, trimming cores and removing proud buds;
t4, harvesting: the cotton is harvested when 1-2 bolls of most cotton plants in the cotton field are opened, and the cotton is harvested every 7-10 days or so. Pulling out the stem when the average green ring of the plant does not exceed 2 in the middle and last ten days of 11 months; the height of the cotton stalk is between 150 and 180cm, and the cotton lint yield is only 180 kg/mu. In the growth process of cotton seedlings, the spraying method and the using amount of the pesticide are the same as those in the example 1, and mepiquat chloride and quizalofop-p-ethyl are not sprayed.
It can be seen that the fertilizing amount in the comparative example 1 is much higher than that of the cotton planting method provided by the application, the yield is lower than that of the cotton planting method provided by the application, and the planting time is about two months longer than that of the cotton planting method provided by the application; in addition, the cotton stalks are higher, the cotton boll opening is not concentrated, and the mechanical harvesting can not be realized.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
