抛秧与直播栽培水稻由于根层分布比较浅，容易倒伏，这是夺取高产的一大障碍。试验证明：拔节期间搁田，结合施用烯施唑与钾肥，能增强水稻自身抗倒能力，对籼稻和粳稻都有显著防倒效果。使用烯效叹和钾肥搁田有明显的防倒效果：一是促进基部节间变短、变粗，早稻倒2－4节反应 Throwing seedlings and direct-seeded cultivation of rice as the root distribution is relatively shallow, prone to lodging, which is to capture a major obstacle to high yield. The results showed that the combination of enzole and potash could increase rice self-lodging resistance and had significant anti-dumping effects on indica and japonica rice. The use of alkene sigmoid potassium field and Tin has obvious anti-down effect: First, to promote the basis of internodes shorter, thicker, early rice inverted 2-4 section reaction
