In 1983—1984, field and pot experiments were conducted to study the interaction between boron and potassium in cotton nutrition. The main results obtained are summarized as follows: 1. Boron and potassium significantly affected cotton yield and there was also a significant interaction between the effects of B and K on cotton yield. When B was severely deficient, potassium was negatively related to cotton yield and vice versa. 2. Symptoms of B-deficiency were aggravated, while the B toxicity...

In 1983—1984, field and pot experiments were conducted to study the interaction between boron and potassium in cotton nutrition. The main results obtained are summarized as follows: 1. Boron and potassium significantly affected cotton yield and there was also a significant interaction between the effects of B and K on cotton yield. When B was severely deficient, potassium was negatively related to cotton yield and vice versa. 2. Symptoms of B-deficiency were aggravated, while the B toxicity Sympotoms alleviated with increasing K content in the soil. 3. B concentration of cotton leaves markedly increased with increasing of B in soil, and decreased with increasing of K in soil. At B-deficient level, total B absorbed by cotton leaves decreased with increasing of K in soil; at moderate and high B levels, moderate K acclerated but high K inhibited total B absorbed by cotton leaves. There were no difference in K content of leaves at any given B levels in soil. But total K absorbed by the plant decreased at low boron and high boron levels. 4. B deficiency significantly affected the anatomical structure of pollen and peticles, and lots of precipitates accumulated in peticle cells, but no influence by K and B level was found.

1983—1984年,在田间及盆栽条件下,进行棉花硼、钾营养及其相互关系的研究,结果表明:硼与钾均呈显著影响棉花产量,且硼、钾间存在相互效应。严重缺硼时,钾与产量呈负相关,高硼时,钾与产量呈正相关;缺硼与高硼均使棉花产生明显的外部症状,且缺硼症状随施钾量的增加而加重,硼中毒症状则随钾量的增加而减轻;叶片含硼量随土壤施硼量的增加而增加,随土壤施钾量的增加而减少;单株叶片吸硼量同样随硼的增加而增加,但与钾的关系则与不同硼水平有关,缺硼时,钾抑制硼的吸收,正常硼及高硼时,中量钾促进硼的吸收,高钾又抑制硼的吸收。叶片含钾量不受土壤施硼量的影响,但缺硼及高硼均使单株叶片吸钾量降低,缺硼严重影响花粉粒的形态及叶柄组织的解剖结构,且缺硼叶柄细胞中存在大量淀积物,高硼及缺钾均不影响解剖学结构,也未发现硼、钾相互关系对它们的影响。

The apple trees (cv. Liaofu/ M. prunifulia Borkh) in pot culture were applied with H 3 10 BO 3 with 93.3% abundance at B 2.0mg·kg -1 soil in the autumn of 1991. The plant and soil were sampled from the spring of 1992 to the spring of 1993. The results showed that, the change of total boron indicated a bimodal curve in aerial part during growing season and an unimodal curve in root. The total boron in cortex of thick root, shoot and trunk was 3~4 times higher than that in xylem, but the...

The apple trees (cv. Liaofu/ M. prunifulia Borkh) in pot culture were applied with H 3 10 BO 3 with 93.3% abundance at B 2.0mg·kg -1 soil in the autumn of 1991. The plant and soil were sampled from the spring of 1992 to the spring of 1993. The results showed that, the change of total boron indicated a bimodal curve in aerial part during growing season and an unimodal curve in root. The total boron in cortex of thick root, shoot and trunk was 3~4 times higher than that in xylem, but the percentage of the 10 B absorbed from 10 B fertilizer in total boron (Bdff%) showed no significant difference between them. Bdff% value of new organs above ground rised sharply in shoot rapid growth period, and then it remained at a high level. Bdff% value in fine roots decreased with advance of time, but increased slowly in thick roots . The Bdff% value in different organs in the third year after B applied in autumn was still 12.7%~33.6%, while only 4.2% in soil. More over, distribution of 10 B in plants changed. The 10 B in the one-year-old shoots and thick roots in 1993 was 2 times higher than that at the sametime in 1992. Trunk and fine roots was significantly lower, which indicated that B in plant tissue could be reused, and it had a long effect.

对盆栽苹果树施H310BO3,于主要物候期测定,结果表明,生长季地上部全B的变化呈双峰曲线,根系仅出现一次高峰;枝条与粗根皮层的全B量一般比木质部高3~4倍,但从肥料中吸收的B占全B量的百分率(Bdf%)二者相差无几。地上部新生器官在新梢旺长期Bdf%值迅速提高,其后处于高水平的相对稳定期,细根随时间进展不断下降,粗根则缓慢上升。秋施10B肥后的第3年花期测定植株不同器官的Bdf%值仍可达12.7%~33.6%,而土壤仅为4.2%,并且10B在植株中的分布发生了变化,一年生枝与粗根含量显著上升,约比翌年同期增加2倍左右,而主干与细根含量显著下降,说明硼肥在树体内具有长效作用,可再利用。
