| 摘 要： | 采用花生光解除草专用膜对泉花10号进行覆膜栽培不同播期试验(3月5日、3月20日和4月5日),结果表明,早播(3月5日)产量最高,比4月5日播种增产极显著,增产的主要原因是早播延长了营养生长期,苗期至花期花生植株较高、叶面积系数大、干物质积累多,而且花期长,后期光合产物转移快,分配到生殖器官多,果多、果大、果饱,因而V/R值小,经济系数高。本试验条件下,花生覆膜栽培播期以3月上旬为宜。

| Abstract: | Mulched cultivation experiments with plastic film were conducted using peanut photolysis herbicide special plastic film and peanut variety Quanhua 10.The results showed that there was highest pod yield for the peanut sowing early(on March 5) among three sowing date treatments,it was extremely significantly higher than that of peanut sowing on April 5.There were many advantages for peanut sowing early(on March 5),such as longer vegetative growth period,taller plant in seedling stage,larger leaf area indexes,more accumulation of dry biomass,and longer flowering period,higer carrying speed of photosynthetic products at late growth stage,more partition ratio in reproductive organ,more pods per plant,bigger plump pods,declined V/R value and higher economic coefficients.These advantageous characters mentioned above were major reasons for early sowing peanut to gain high pod yield.Under the conditions of this experiment,the optimum sowing date was early March. |
