摘要
以５种保水剂为材料配制的胶状悬浮液，在土壤含水量不足１３．６％的情况下应用，保证了一播全苗，且５～０ｃｍ土壤含水量提高４．５％～１８．１％。芝麻各个生育期均比对照提前，叶面积系数增加０．５４％～１．９９％，单株侧报数增加７条，根长增加１１．２ｃｍ，２４小时根伤流量增加３４．５％～４０．２％．对苗期立枯病防效达９６％，对枯萎病、茎点枯病、病毒病的防效均在６０％以上．三年平均增产６４．５％。
Abstract kinds of colloid which 5 water preserving agents as basic materials were used in sesame fluid sowing in drought area where soil moiture capacity was below 13. 6 %.The fluid sowing was superiority to conventional sowing as follows: 1 )the germination percent was markedly hish and the soil moisture capacity in 5～10cm layer was raised by 4. 5%～18. 1%. 2) LAI,number and length of roots per plant increaed by 0. 54～1. 99,7 and 11. 2cm respectively. 3) Control effectiveness to Rnizotconia soianl, Fusarium vasinfectum Var. sesami and Macrophomina phasevli were 96 %, 69. 6 % and 66. 8% respectively and the yield increased by 64. 5 %
