据无锡市郊区黄巷乡高泾农科队、侣元乡东顾巷农科队等8个点试验证明,碳铵底施不仅能提高产量,还能增强蔬菜的抗病能力。 试验分碳铵不同用量底施与追施水粪两项。品种为矮脚黄和矮杂1号青菜。播种期为9月8～11日,定植期为10月4～12日,是历年秋季病毒病发生最严重的时期。小区顺序排列,均重复三次。碳铵在定植前一天按规定用量撒在畦面上,立即浅混土。水粪于青菜生长期中每次用20担泼浇。试验除测定产量外,对其生长速度及病毒病发生程度也进行了定期调查。
According to the Wuxi suburbs Huangxiang Township High-Agricultural Science Team, Rural Township, Lane Township, East Township Departmental Research 8 points prove that the bottom of ammonium bicarbonate can not only improve the yield, but also enhance the resistance of vegetables. Test points different levels of ammonium bicarbonate at the end and topdressing two water excrement. Variety of short yellow and dwarf miscellaneous vegetables on the 1st. The sowing period is from September 8 to September 11, and the planting period is from October 4 to December 12, the most serious period of virus disease in autumn. Cell order, are repeated three times. Ammonium bicarbonate in the day before planting according to the provisions of the amount of sprinkle on the surface, immediately mixed with soil. Water excrement in the growth of vegetables each with 20 Tam pouring. In addition to testing the yield test, its growth rate and the extent of viral disease have also been regularly investigated.
