近年来,我们在绵阳丘陵区进行两熟制稻田增种晚秋蔬菜的试验和大面积推广工作,初步总结出一些夺取稻田晚秋蔬菜高产的有效经验。一、小厢密植晚秋蔬菜生长发育较快,50—60天即收获,单株产量较低。必须保证有较大的密度才能夺高产。如早熟白菜须达到5000株/亩;早熟萝卜10000—15000株/亩;莴苣8000—10000株/亩。对其它作物也必须掌握“以密取胜”的原则。为了保证密度,田间一般不预留小春作物播栽的空行而实行满种,多采用以1.5—
In recent years, we conducted experiments and large-scale popularization of late-cropping vegetables in two-cropping paddy fields in Mianyang hilly areas, and initially summed up some effective experiences in capturing late-yielding vegetables in paddy fields in late autumn. First, the small densely populated Late autumn vegetables grow faster, 50-60 days that harvest, lower yield per plant. Must ensure that there is a greater density to win high yield. Such as precocious cabbage to reach 5000 plants / mu; precocious radish 10000-15000 plants / acre; lettuce 8000-10000 plants / acre. Other crops must also master the principle of “winning by winning in secret.” In order to ensure the density of the field generally do not set aside blank rows of small crop planting and implementation of full species, and more to 1.5-
