近年来花生早熟品种种植面积不断扩大,但在早熟花生栽培过程中常出现旱象,对产量影响很大。为此,1981年我们以目前推广的花生早熟良种白沙1016为供试材料,研究其主要生育期对干旱的影响。通过试验找出不同生育期临界水分,为花生生产提供科学的灌水依据。 一、材料与方法 试验采用池栽,生育期间利用塑膜棚覆盖,人为控制水分,在花针、结荚、饱果期造成不同干旱条件,以研究其对花生生长发育的影响。
In recent years, planting area of peanut precocious varieties has been constantly expanding, but in the process of early maturing peanut cultivation appears drought, a great impact on the yield. To this end, in 1981 we are currently promoting the peanut early seed Baisha 1016 as a test material to study the main growth period of the drought. Through experiments to find the different critical stages of the growth of water for peanut production to provide a scientific basis for irrigation. I. Materials and Methods The experiment was carried out in ponds. During the growth period, plastic film sheds were used to cover the artificial water. Different drought conditions were caused during flower stabbing, podding and full-fruiting periods to study their effects on the growth and development of peanuts.
