沿江高沙土砂粒含量高,有效土层浅,养分储量低,漏水、漏肥严重,作物易早衰,产量低而不稳。针对高沙土这一特殊土质,我们通过近几年试验、示范,摸索出高沙土地区小麦高产施肥新措施。1适施基肥 高沙土的特点是“发小不发老”,且漏水、漏肥严重,故基肥以有机肥为主,亩施粪肥1000～1500kg或杂灰1～2m~3,并配施硅肥10kg/亩。2施足苗肥与壮蘖苗 麦苗一叶一心和四叶一心时 Sandy sand along the high sandy soil content, effective soil shallow, low nutrient reserves, leakage, serious leakage of fertilizer, crop premature aging, low yield and instability. In view of the special soil with high sandy soil, we try out new measures of high-yield wheat fertilization in high sandy soil area through experiments, demonstration and exploration in recent years. 1 suitable for basal high sandy soil is characterized by "hair small non-old, and leakage, serious leakage of fertilizer, so the basic fertilizer organic fertilizer, mu manure 1000 ~ 1500kg or 1 ~ 2m ~ 3 mixed ash, and with facilities Silicone fertilizer 10kg / mu. 2 Shizuosu enough fertilizer and sprout seedling wheat leaves one heart and four leaves one heart
