摘要:

【目的】筛选新疆北疆花生生产上适宜的播期和种植密度。【方法】以花育25为供试品种,采用两因素裂区试验,设置5月3日、5月10日和5月17日3个播种时间,4个种植密度分别为13.0×104 、14.5×104 、16.0×104 和17.5×104 穴/hm2,分析播期和种植密度对花生农艺性状、干物质积累、产量及品质的影响。【结果】在相同种植密度下,随播期推后,花生主茎高、分枝数以及叶面积指数均呈降低趋势;花生干物质积累量以及产量则呈先增大后降低趋势,在5月10日播期处理时最高;花生蛋白质、脂肪以及油酸含量均在5月3日播期处理时最高。种植密度对花生各生育时期农艺性状也均有显著影响,密度过高和过低均不利于花生干物质积累和产量形成,低密种植时更有利于提高花生籽粒品质。【结论】播期和密度互作对花生整个生育期生长发育的影响均显著。新疆北疆花生宜播种时期为5月3~10日,适宜种植密度在14.5×104~16.0×104 穴/hm2

Abstract:

【Objective】To clarify the appropriate sowing date and planting density of peanut production in northern Xinjiang.【Methods】Huayu 25 was used as the test variety. The experiment was designed with three sowing dates of May 3, May 10 and May 17, and four planting density levels of 13.0×104, 14.5×104, 16.0×104 and 17.5×104 holes/hm2, to analyze the effects of sowing date and planting density on agronomic traits, dry matter accumulation, yield and quality of peanut.【Results】With the push of the sowing date, the main stem height, the number of branches and the leaf area index all decreased at the same planting density. The accumulation of dry matter and yield increased first and then decreased, with the highest treatment on May 10. Peanut protein, fat and oleic acid levels were the highest on May 3. Planting density also had a significant effect on the agronomic traits of peanut during each reproductive period, too high and too low planting density were unfavorable to the accumulation of dry material and yield, low-density planting was more conducive to improving the quality of peanut seeds.【Conclusion】The sowing period and density interaction significantly affect the growth and development of peanut throughout the growth period. The suitable sowing time of peanuts in northern Xinjiang is between May 3 and May 10, and the planting density is from 14.5×104 to 16.0×104 holes/hm2.
