硼锌微量元素对遇冷害黄瓜恢复生长的效果

Effect of Using Microelement Bo and Zn to Recover the Growth of Cucumbers with Cold Damage

于2007年2月20日至2007年5月30日在钦州市钦南区大番坡镇龙眼坪村陆永仪试验田进行及时施用微量元素硼锌来促进遇冷害黄瓜苗正常生长的恢复试验。试验田面积为1.5hm2,黄瓜品种为加工型黄瓜"钦育一号"。试验喷施0.2%磷酸二氢钾+硼砂1000倍液+硫酸锌1000倍液+0.3%尿素混合液,以叶面肥的形式喷施,黄瓜苗统计恢复生长后的产量,重点记录12株黄瓜苗的恢复生长情况,并以清水喷施遇冷害出现"花打顶"的黄瓜苗作对照。结果1.5hm2试验地共采收鲜黄瓜14575kg,平均每公顷收鲜黄瓜9937.5kg;喷施硼锌的12株黄瓜苗共收黄瓜34个,对照的12株黄瓜苗共采收到黄瓜21个,喷施硼锌比对照多收黄瓜13个,增收61.9%。

Test was made at Lu yongyi Dafanpo Longyanping Qinnanqu Qinzhou City Guangxi from February 20,2007 to May 30,2007. The test used microelement Zn and Bo to Promote the recovering growth of cucumber plants which had been cold damaged. The experimental field is1.5 hm^2, and the test cucumber breed is ＂Qin yu No1＂. The blend liquid of 0. 2 % KH2PO3, 1000 times H3BO4 and 0.3 % Urea were used as the leaf faces fertilizer. The recovering condition is 12 plants using the blend liquid and the other 12 plants using water as contrast. The yield of plants was observed and recordered. The results showed that 1.5hm^2 experimental field harvest fresh cucumber 14575 kg,which the average is 9937.5kg/hm^2. 12 plants using the blend liquid of Zn and Bo collected 34 cucumbers and the contrasts received 21 cucumbers. The former is 13 cucumbers more than that of the later,which increased to 61.9%.
