以原丰早为材料进行了在不同时期施用植酸与氯离子的试验。在水稻抽穗至成熟期间叶面喷施植酸，能抑制水解酶类的活性，减弱淀粉酶分解淀粉的反应，提高淀粉合成酶的活性，有利于淀粉合成，改善稻米品质。水稻齐穗期叶面喷施５０、１００ｍｇ／ｋｇ两种浓度的植酸，碎米率的平均值比对照低２．８～３．１个百分点，整精米率上升５～７个百分点；垩白等级、垩白率降低，乳白米粒减少，与对照相比差异显著；对碱消值、直链淀粉含量亦有影响。氯离子作为淀粉酶的激活剂，喷施后能抑制淀粉合成酶的活性，对稻米品质呈逆向效应。
The experiment of applying phytic acid and chloride ion in different periods was carried out by using the raw material of Asahi early morning. Phytase phytochemicals foliar spraying during heading to maturity can inhibit the activity of hydrolytic enzymes, weaken the reaction of amylase to decompose starch, improve the activity of starch synthase, is conducive to starch synthesis and improve the quality of rice. At the heading stage of rice, phytates were sprayed at the concentrations of 50 and 100mg / kg, the average broken rice rate was 2.8 ~ 3.1% lower than that of the control and the rate of milled rice was increased by 5 ~ 7% White grade, chalkiness rate decreased, milky white rice decreased, compared with the control significant difference; the value of alkaline consumption, amylose content also have an impact. As an activator of amylase, chloride ion can inhibit the activity of starch synthase after spraying and has a reverse effect on the quality of rice.
