沼肥在玉米生产上施用效果初探

目的]为沼气副产物的利用及玉米的高产栽培提供科学依据。方法]在玉米栽培试验中,设3个处理:清水浸种,不施沼肥A为对照;以沼液浸种后用沼渣作营养块为基础,在苗期和抽穗期不施用沼液为B,施用沼液为C。结果]与对照相比,处理B和C都能明显促进玉米的生育进程,分别使玉米生育期缩短4和7 d,沼液浸种能使玉米出苗期缩短2 d;B处理的株高、茎粗、穗位高、穗粗、穗重、穗行数、行粒数、千粒重分别增加2.65%、02、.33%8、.77%2、3.53%、12.50%2、5.99%、2.94%。C处理的分别增加3.59%、4.17%、5.99%、8.77%5、0.00%、12.50%、20.06%、10.68%。C和B处理的小区平均产量分别达39.10和35.10 kg,与对照相比分别增产15.99%和4.72%,C处理的产量显著高于对照。结论]作为沼气副产品的沼渣、沼液对玉米发芽、出苗及高产栽培都有一定的促进作用。

Preliminary Exploration in the Application Effect of Biogas Manure on Maize Production

Objective] The purpose of the research was to supply scientific basis for the utilization of biogas byproducts and the high-yield cultivation of corn.Method] In the experiment of corn cultivation,3 treatments were set up as: rinsing soaking seeds without applying biogas liquid as A(CK),on based of biogas dregs mix nutrition soil after biogas liquid soaking seeds,without applying biogas liquid as B and with applying biogas liquid in seedling and heading stage as C.Result] Compared with CK,both the treatments B and C could promote the growing process of corn and shortened the growth period of corn for 4 and 7d resp.;seed-soaking with biogas slurry could shorten the seedling emergence period of corn for 2 d;the plant height,stem thickness,ear height,ear thickness,ear weight,row number per ear,grain number per row and 1 000-seed weight in the treatment B increased 2.65%,0%,2.33%,8.77%,23.53%,12.50%,25.99% and 2.94% resp.and that in the treatment C increased 3.59%,4.17%,5.99%,8.77%,50.00%,12.50%,20.06% and 10.68% resp.The average plot yields in the treatments C and B reached 39.10 and 35.10 kg resp.,being 15.99% and 4.72% higher than CK resp.The yield in the treatment C was significantly higher than that in CK.Conclusion] As biogas byproducts,biogas residues and slurry had some promoting effects on the germination,seedling emergence and high-yield cultivation of corn.
