一、改土培肥及增产的效果种植草木樨对抑制土壤返盐,促使淋盐和改土培肥,提高粮棉产量具有一定的作用.据测定:寄种或翻埋草木樨后,0～30厘米土层氯盐量从0.15%降至0.8～0.12%,土壤容重减轻0.08～0.10克,水稳性团粒结构增加4.0～5.4%,土壤硝态氮、速效磷增加2.1ppm和2.Oppm.翻埋后,在土壤水分充足情况下,6天后土壤速效养分显
First, the soil fertility and increase the effect of planting grass mulberry inhibit soil salt back to promote salt and soil fertility training to improve the yield of grain and cotton has a certain role.According to the determination: After planting or burying grass mulberry, 0 The amount of chloride in ~ 30 cm soil layer decreased from 0.15% to 0.8 ~ 0.12%, the soil bulk density decreased 0.08 ~ 0.10 g, the water stable aggregate increased by 4.0 ~ 5.4%, the soil nitrate nitrogen and available phosphorus increased by 2.1 ppm and 2. Oppm. After burial, soil available nutrients were significant after 6 days under sufficient soil moisture
