施用镁硼钼肥对山地紫色土烤烟产质量的影响

以NC297为材料,通过田间试验研究了施用镁硼钼肥对山地紫色土烤烟产质量的影响。结果表明:紫色土施用镁、硼、钼肥能有效促进烟株早生快发,延长生育期,改善烟株农艺性状,提高烤烟经济效益、工业可用性;同时施用镁、硼、钼的T4处理的经济性状、化学成分最好,施用硼的T2处理评吸质量最好,施用钼的T3处理各项指标中偏上,施用镁肥的T1处理烟叶等级结构最好,CK处理除化学成分协调性较好外,其他指标均较差。

施用硼、钼肥对不同刈割期紫花苜蓿产量及粗蛋白含量的影响

为了解不同茬次的紫花苜蓿在施用微肥后产量及粗蛋白含量的变化,本试验采用单因素设计,以3年生金皇后为试验材料,研究了硼、钼肥对刈割4茬紫花苜蓿的株高、草产量及粗蛋白含量的影响。结果表明:4次刈割对紫花苜蓿株高和草产量影响为:第2茬>第1茬>第3茬>第4茬;且施用硼、钼肥处理株高和产量均高于不施肥处理。其中硼肥以B2(硼喷施0.2%)处理最高,钼肥处理以M2(钼喷施0.1%)处理最高,且喷施硼、钼肥的效果优于基施;无论是施硼肥还是钼肥,粗蛋白含量的变化趋势均呈反“L”形变化,其中刈割第4茬粗蛋白含量最高,第3茬最低,1茬、2茬次之。

黑龙江省食用向日葵施用硼锌钼肥效果初探

为了提高黑龙江省食用向日葵产量,以食用型向日葵品种龙食葵2号为试材,研究了不同的硼、锌、钼组合肥料处理对食用向日葵的农艺性状、产量性状的影响。结果表明:不同施肥处理有利于提高食用向日葵株高、茎粗;不同施肥处理有利于提高食用向日葵单株总粒数、单株成粒数、单株籽实重、百粒重、百仁重、结实率和产量,其中百粒重、结实率增效显著;不同施肥处理对食用向日葵产量的提高主要是通过增加其百粒重和结实率实现的。

施肥对鲜食蚕豆鲜荚和地上部产量的影响

采用裂区设计研究磷钾肥不同用量和花期喷施硼钼肥对鲜食蚕豆鲜荚产量和地上部生长量的影响。结果表明,适量施用磷钾肥时,能增加鲜荚产量,667 m2施磷肥(P2O5)4 kg,钾肥(K2O)3 kg产量最高,但对地上部秸秆影响不显著;硼钼肥喷施,硼+钼鲜荚产量最高,喷施钼地上部分产量最高。

干制丘北辣椒高产栽培技术研究

丘北辣椒属于典型的干制线椒,食用风味独特,是文山州最大的出口创汇农产品,但大面积生产每667m2干椒单产不足100kg,远远不能满足产业发展需求。为探讨辣椒高产栽培技术,设计了密度,N、P、K肥配比,B、Mo肥配比的3因素3水平正交试验。试验结果表明:当密度为4500株/667m2,N、P、K配比为16:12:17,B、Mo肥配比为1:2时,丘北辣椒每667m2干椒单产达274.7kg,最佳组合是A3B3C2处理。

Effects of B, Mo, Zn, and Their Interactions on Seed Yield of Rapeseed (Brassica napus L.)

A field experiment was conducted to study the effects of boron (B), molybdenum (Mo), zinc (Zn) and their interactions on seed yield and yield formation of rapeseed (Brassica napus L. var. Huashuang 4). Application of B fertilizer to a sandy soil increased the seed yield by 46.1% compared to the control and also created a considerably higher seed yield than the two treatments solely applying Mo and Zn fertilizers, which suggested that B was a main constraint for the seed yield of Huashuang 4 in this experiment. The effect of B fertilizer on the seed yield was attributed to an increase in the number of seeds per silique and siliques per plant. The combined application of B with Mo or Zn resulted in higher seed yield than the application of B, Mo or Zn alone, and the seed yield of the B+Mo+Zn treatment was the highest in all treatments, 68.1% above the control. Dry matter accumulation of seed followed a typical S-shaped curve and it was higher in plants supplied with B than in plants without B. A small but significant increase in the seed oil content and an improvement in the oil quality were also observed in all treatments compared with the control. These results suggested that optimal micronutrient application could provide both yield and quality advantages for rapeseed in poor soil.
