本试验用三种激素各配成不同浓度的溶液,定期喷洒苎麻幼苗,观察分析了植株的生长、根系发育、干物质累积以及光合强度、养分吸收等生理功能的表现。结果表明,以三十烷醇0.5ppm处理的麻苗长势最好,而赤霉素100ppm 处理的麻苗,在株高、光合强度等方面,也有极明显的反应。

TA could stimulate NK activity induction by KNO3 in Pinus elliottii Engelm. seedlings at different ages. TA could not induce NR activity alone, but could enhance NR induction by NO3. TA eliminated partially the inhibition of arsenate (an oxidate phosphorylation decoupler). The accumulation of chlorophyll accelerated by TA or BA closely paralleled to the increase of NRA accelerated by TA or BA. Cycloheximide (CHM) could inhibit the effect of TA on NRA in roots and excised etiolated leaves exposed to light and...

TA could stimulate NK activity induction by KNO3 in Pinus elliottii Engelm. seedlings at different ages. TA could not induce NR activity alone, but could enhance NR induction by NO3. TA eliminated partially the inhibition of arsenate (an oxidate phosphorylation decoupler). The accumulation of chlorophyll accelerated by TA or BA closely paralleled to the increase of NRA accelerated by TA or BA. Cycloheximide (CHM) could inhibit the effect of TA on NRA in roots and excised etiolated leaves exposed to light and NO3. Lincomycin (LCMC, an inhibitor of chloroplast protein synthesis) could only inhibit the effect of TA in etiolated leaves, but did not inhibit the effect of TA on NRA in roots. The inhibition of CHM was much stronger than LCMC.

卅烷醇(TA)0.5和1.0ppm对不同苗龄湿地松幼苗硝酸还原酶(NR)活力诱导均有促进作用。TA不能单独诱导NR活力,但它能促进NO_3~-对NR的诱导。TA能部分抵消砷酸钠对NR活力的抑制。TA促进黄化苗叶绿素的积累紧密平行于它对NR诱导的促进。CHM对TA促进黄化针叶及根的NR诱导有明显的抑制作用,而LCMC只抑制TA对针叶的效应,不抑制TA对离体根的作用。经TA处理的湿地松幼苗,其高生长、根系生长及各器官的生物量均显著高于对照。

The study on the effect of phosphoric fertilizer on the growth,root distribuhon and yield of dryfarming pea was conducted under field condition.ResultS showed that phosphoric fertilizer applied promoted the growth above ground,increased the root amount,expended the root distribution range, raised the number of pod and grain weight per plant and increaded the yield.The variation of the plant height,number of stem node and dry weight above ground with growing time were simulated by logistic Equation. and the changement...

Under the experimental condition the most economical amount or phosphoric fertilizer was 1011.0kg, superphosphate per ha.

本文利用田间分期取样,研究了旱作条件下施用磷肥对豌豆地上部生长、根系分布和产量的影响.结果表明,施用磷肥显著促进豌豆地上部生长,增长根量,扩大根系范围,增加单株荚数、粒重、提高产量.不施磷与施磷肥下,豌豆株高、主茎节数的地上干物重随生育期的变化均可用Logistic方程描述,而一定土体内单株根长随上层深度和生育期的变化可用非齐次的二元多项式模拟.在本试验条件下,豌豆磷肥的经济最佳施用量为每亩67.4kg过磷酸钙.
