The Effect of Quantity and Efficiency Coordinated Cultivation Techniques on Wheat Development,and Yield in Huaibei Area
In order to verify the coordinated cultivation technology of quantity,quality and efficiency of wheat,and study the effects of different sowing dates,sowing amounts and fertilizer operations on wheat growth,development and yield in Huaibei area,the local real estate variety Xumai2100 was selected as the test material,and the experiment on the effects of coordinated cultivation technology of quantity,quality and efficiency on wheat growth,development and yield in Huaibei area was car-ried out in 2022-2023.The results showed that sowing date,sowing amount and fertilizer operation significantly affected wheat growth process,seedling quality and yield.In terms of population quality and yield,the effect of spraying irrigation before sowing was better than that after sowing.With the delay of sowing date,the accumulated temperature from sowing to emergence increased,the whole growth period shortened,and the accumulated temperature decreased.The leaf age of main stem decreased,the total number of tillers per acre,the number of tillers per plant,the number of large tillers of ≥3.1 and 4.1 leaves and the number of roots per plant decreased,the number of ears per acre and the actual yield decreased.The analysis of N amount per 100 kg of grain showed that the unsuita-ble sowing time consumes more fertilizer,not only the yield was low,but also the fertilizer input was large,the cost was high and the benefit was low.The high yield and relative high yield of wheat were mainly due to the early sowing in the suitable period,precise sowing and reasonable fertilizer opera-tion.
