(一) 刈割时期:分期刈割绿色产量以5月15日产量最高,6月25日次之,8月13日又次之,11月5日产量最低;9月下旬刈割植株无萌发力。(二) 小肥养大肥:以亩施尿素、过磷酸钙各30斤的肥效最好,比亩施各60斤的增产47.85%,比不施肥的增产53.22%。(三) 日照温度:气温27.9℃、土温21.3℃,最适宜植株生长。日照10小时比日照G小时增产46.3%,比日照3小时增产89.67%。(四) 根的特性:一年生新根越粗,根的生长量越大。春季断根结合施肥,可以恢复根的生长势,断根不施肥,会削弱根的生长量。
(I) Mowing period: The mowing period of green production was the highest on May 15, followed by June 25, followed by August 13, and the lowest on November 5; the mowing plants did not germinate in late September force. (B) small fattening fat manure: Urea urea, superphosphate 30 kg of the best fertilizer efficiency than the 60 kg of Mushu yield 47.85% increase of 53.22% than the non-fertilization. (C) sunshine temperature: temperature 27.9 ℃, soil temperature 21.3 ℃, the most suitable plant growth. Sunlight 10 hours than G hours sunshine 46.3% increase, 3 hours more sun-yield 89.67%. (D) the characteristics of the root: the annual new root thicker, the greater the growth of the root. Spring combined with root and root fertilization, can restore the root growth potential, without root fertigation, will weaken the root growth.
