一、育苗移栽的好处(一)玉米和绿肥双增产:我县玉米的前茬多是麦草夹作。过去,玉米一般在4月上旬播种,由于绿肥苗小,鲜草产量低,一般亩产只有500—600斤。如果将玉米的播期推移到4月下旬,虽然鲜草产量可以大大提高,但玉米的产量受影响。采用玉米育苗移栽,既可保证玉米适时早播,又可使绿肥长到4月底、5月初。沈灶公社红日大队第五生产队试验,3月28日直播的玉米地块,亩产鲜草600斤,玉米462斤,与直播同期育苗、5月2日移栽的,亩产鲜草2,654斤,玉米560斤。
First, the benefits of transplanting seedlings (A) Double increase in corn and green manure: I County corn stubble is more for the pasture. In the past, corn was generally sown in early April. Due to the small size of green manure and low yield of fresh grass, only 500-600 jin per mu was generally produced. If the sowing date of corn is shifted to the end of April, the yield of maize will be affected although the yield of fresh grass can be greatly increased. Transplantation of corn seedlings, corn can not only ensure timely sowing, green leaven can grow to the end of April, early May. Shenzao commune red brigade fifth team test, live on March 28 corn plots, fresh grass yield 600 pounds, 462 kg of corn, seedlings with live broadcast over the same period, May 2 transplanting, yield fresh grass 2,654 pounds, 560 pounds of corn.
