在麦后稻前种(养)一茬柽麻或田菁、绿豆、细绿萍,作为水稻底肥,14个试验点的水稻增产效果明显,并能降低土壤容重,增加土壤孔隙度,土壤有机质和全氮等均比对照提高,麦茬绿肥掩青对肥田改土有良好作用。麦茬后种植柽麻宜在5月底6月初,采用整地播种或铁茬播种,及时灌“跑马水”,种量4～6公斤/亩。种植绿豆力争早播,豆种要在种前浸泡。田菁可分育苗移栽和直播两种方式,施用磷肥可提高产草量。细绿萍于麦收后灌水7～10cm,放萍种150～200公斤/亩,养殖40天,鲜萍产量可达2690公斤/亩。
The results showed that paddy or Shitianjing, mung bean and fine green alsophila had the obvious effect of increasing yield of paddy rice at 14 test points and reducing the bulk density of soil, increasing the porosity of soil, increasing the soil organic matter And total nitrogen increased compared with the control, wheat stubble green manure on soil fertigation improved soil has a good effect. After the stubble cultivation of flaxseed should be at the end of May early June, using sowing or sowing planting, timely irrigation “Happy Valley”, the amount of 4 to 6 kg / acre. Strive for early planting of mung bean cultivation, bean species to soak before the species. Tian Jing can be transplanted nursery seedlings and live broadcast in two ways, the application of phosphate fertilizer can increase the amount of grass. Fine green Pingmei harvest after the wheat irrigation 7 ~ 10cm, put Pingchuang 150 ~ 200 kg / mu, breeding 40 days, fresh ducklings up to 2690 kg / mu.
