采用盆栽及田间试验观察了气温对果针入土后荚果发育的影响,结荚期间与气温的关系以及始花期后气温对产量的影响。盆栽试验,供试品种为半蔓大花生千叶半立。1967年于4月15日、5月15日、6月14日及7月14日四期播种,1968年5月22日播种。两年试验均从7月至9月每10天一次将入土果针加以标记,以便识别。于花生生育期间每隔10天取样一次观察不同时期入土的果针荚果发育过程。田间试验于1967年进行,供试品种与播种期次均与盆栽试验相同,10月7日收获。试验结果如下:
The effects of temperature on pod development after pod needling were investigated by pot and field experiments, the relationship between pod temperature and pod temperature, and the effect of temperature on the yield after the initial flowering stage. Pot experiment, the test varieties of semi-manna peanut Chiba half stand. 1967 April 15, May 15, June 14 and July 14, four seeding, May 22, 1968 sowing. Two years of testing from July to September once every 10 days will be marked to identify the needle. During the growth period of peanut, samples were taken every 10 days to observe the pod development during the different periods. Field trials in 1967, the test varieties and seeding times were the same with the pot experiment, October 7 harvest. The test results are as follows:
