地膜小麦较常规小麦0~10cm地温提高2.25~2.82℃;0~10cm、11~20cm、21~30cm、31~40cm、41~50cm土壤含水量依次比CK提高1.96%、1.34%、2.32%、1.64%和1.04%;穗分化提前3~5d;分蘖质量和数量均发生了显著变化。冬前、返青和拔节期的增蘖幅度依次为11.5%、30.3%和10.6%;成穗数增加9.7%;扩源增库效果显著,拔节到抽穗期主茎叶面积增加11.5%~30.4%,各器官物质积累量大幅度提高,产量结构发生明显变化,成穗数增加52.5万/hm2,穗粒数增加4.6粒,每公顷净增产1306.5kg,增产幅度22.6%。
The soil temperature of 0-10 cm, 11-20 cm, 21-30 cm, 31-40 cm and 41-50 cm of wheat increased by 1.96% compared with that of CK, 1.34%, 2.32%, 1.64% and 1.04% respectively. Spike differentiation was 3 ~ 5 days earlier. The quality and quantity of tillers changed significantly. The tillering rates before winter, returning to green and jointing were 11.5%, 30.3% and 10.6% respectively, the number of spikelets increased by 9.7% Leaf area increased by 11.5% ~ 30.4%, the accumulation of various organs increased significantly, the yield structure changed significantly, the number of spikelets increased by 525000 / hm2, grain number increased by 4.6 grains per hectare Net increase of 1306.5kg, increase rate of 22.6%.
