一般种植芦笋,当年播种育苗,次年定植,第三年采笋,见效迟且初期产量不高,因而影响了农民的经济收入和种植积极性。如能提早播种,就可实现当年定植,达到提早采收增加产量的目的。为了解决提早育苗受早春低温影响的矛盾,我们进行了塑料大棚育苗技术研究,以达到当年育苗当年定植,提早采笋的目的。材料和方法 1.大棚和露地育苗技术对比试验: 1987年:大棚和露地平畦育苗。品种uc800;面积各为97.2平方米;株行距0.4 ×0.03米;大棚内和露地均于4月29日播种;
The general planting of asparagus, sowing seedlings that year, the following year planting, bamboo shoots the third year, early and effective early yield is not high, thus affecting the economic income of farmers and planting enthusiasm. If early sowing, planting can be achieved then, to achieve early harvest to increase production purposes. In order to solve the contradiction of early seedling raising affected by the low temperature in early spring, we conducted researches on seedling raising technology in plastic greenhouse so as to achieve the purpose of planting and raising the earliest in the year of seedling raising. Materials and methods 1. Greenhouses and open field nursery technology comparative test: 1987: greenhouse and open field nursery. Varieties uc800; area of 97.2 square meters each; spacing of 0.4 × 0.03 meters; shed and open field were sown on April 29;
