研究表明,石河子地区芦笋植株在栽苗后的第二年生长量最大,表现在分株敷、株高、根茎粗、白嫩茎鲜重以及宽度、厚度与第一年相比增长率依次为7.1%、56.6%、58.8%、63.0%、54.4%和46.3%。因此,第二年生长初期合理施肥对营养体迅速扩大及早期产量的提高均有着重要的意义。以每穴植株地上部干重达220g为目标值,所得优化农艺措施为每穴施尿素13.5~14.28,草木灰17.6~18.3g,三料过磷酸钙18~16.6g,磷酸二铵19.1~19.6g。单项施肥的种类,以磷酸二铵最佳。第三年春所采收嫩茎的单根平均鲜重为18.83g,鲜重的增加与嫩茎宽与厚的增加有直接的关系。采收嫩茎的每穴平均产量约90g。无空心现象。
The results showed that the growth rate of asparagus plants in Shihezi area was the highest in the second year after planting, showing that the growth rate of the plant, plant height, rhizomes, white tender stems fresh weight, width and thickness were 7.1% , 56.6%, 58.8%, 63.0%, 54.4% and 46.3% respectively. Therefore, the second year of early growth of rational fertilization on the rapid expansion of vegetative and early production are of great significance. Taking the shoot dry weight per plant as 220g as the target value, the optimized agronomic measures were 13.5-14.28 urea per hole, 17.6-18.3g ash, 18-16.6g triple-superphosphate, 19.1-19.6g diammonium phosphate . The type of single fertilizer to diammonium phosphate the best. In the third year, the average fresh weight of young stems harvested by spring was 18.83g, and the increase of fresh weight was directly related to the increase of tender stem width and thickness. The average yield per shoot of harvesting stems is about 90g. No hollow phenomenon.
