阳畦菜花早春露地定植,采用塑料小沟棚覆盖可避免早期低温、干旱、冷空气侵袭等不良气象因素影响,促进根系生长,缩短缓苗时间,植株营养生长旺盛,结球早、上市早。一般覆盖菜花上市较露地未覆盖菜花早10—15天,收入增加25—33％左右。塑料小沟棚还有制做简便,材料来源广,成本低,受益大等优点。1982年春我们在孔家崖大队矮荷花菜花上进行前期覆盖小沟棚与未覆盖小沟对比试验:实验结果是覆盖较未覆盖提早上市10天。
Yangzi cauliflower is planted in the open field in early spring. Covering with plastic ditches can avoid the influence of bad weather factors such as early low temperature, drought and cold air invasion to promote root growth and shorten the time for Huanmiao growth. Cover the cauliflower generally uncovered 10-15 days earlier than uncovered cauliflower, income increased by 25-33%. Plastic ditches also easy to make system, wide source of raw materials, low cost, benefit from the advantages. In the spring of 1982, we conducted a preliminary test on the cover of the dwarf cauliflower in the Kongjiaya brigade in comparison with the uncovered minor ditches. The experimental result is that the coverage is 10 days earlier than the uncovered coverage.
