影响旱育秧推广的主要技术障碍是土壤调酸困难,返盐返城,暴发立枯病大量死苗。为解决这一问题,1997～1998年用中国农业大学张军博士发明的移栽灵混剂在旱育秧上进行了试验。现将试验结果总结如下。 1 材料与方法 1.1 供试土壤 黄河冲积性黄潮土,有不同程度的次生盐碱。0～20cm土层含盐量0.15％～0.25％,pH值7.3～8.5。 1.2 供试品种 试验使用品种均为豫粳6号,全生育期150～155d。4月底至5月初育秧,6月10～15日移栽,秧龄45d左右。
The main technical obstacles that affect the popularization of dry nursery seedling are soil acid-adjusting difficulties, returning salt to the city, and outbreak of dead blight. To solve this problem, 1997 ~ 1998 with the China Agricultural University Dr. Zhang Jun invented the transplanting Ling mixture tested in dry nursery seedlings. The test results are summarized below. 1 Materials and Methods 1.1 for the Yellow River test soil alluvial yellow soil, there are different degrees of secondary saline. 0 ~ 20cm soil salt content 0.15% ~ 0.25%, pH value of 7.3 ~ 8.5. 1.2 The varieties tested varieties are Yujing 6, the whole growth period of 150 ~ 155d. The end of April to early May seedlings, June 10 to 15 transplanting, seedling age 45d or so.
