对克新21号施用不同用量的磷肥,研究磷肥对其产量的影响。结果表明,当磷肥用量为4.2g时,克新21号单株产量达到最大值154.25g,克新21号株高随磷肥用量改变并无明显变化。磷肥对克新21号淀粉性状影响较大,随着磷肥用量增加,克新21号淀粉中位径大小与淀粉黏度大小呈现相近变化趋势,当磷肥用量达到3.6g时,克新21号黏度值达到最大值5968cp,中位径达到最大值49.12um。
The effects of phosphate fertilizer on the yield of Kexin 21 were studied using different amount of phosphate fertilizer. The results showed that when the amount of phosphate fertilizer was 4.2g, the yield per plant of Kexin 21 reached the maximum value of 154.25g. The plant height of Kexin 21 had no significant change with the change of the amount of phosphate fertilizer. Phosphorus fertilizer has a great influence on the starch properties of Kixin No.21. With the increase of the amount of phosphate fertilizer, the median diameter of starch of Starch No.21 and the starch viscosity showed a similar trend. When the amount of phosphate fertilizer reached 3.6g, the viscosity of Kexin 21 Reached a maximum of 5968cp, the median diameter reached a maximum of 49.12um.
