为了探索花生高产的途径,自一九七五年以来,我们对花生与气象因素的关系进行了比较系统的观测和试验,四年来,我们观测了花生整个生育期的气温、降水、日照、地温,每五天测定一次土壤5—20公分的墒情,进行了花生丰产田植株生育动态的观测,逐日开花量记载和地下生长速度的测定。除此之外还进行了播种期,浇水,保墒增温剂等辅助试验。几年的观测试验和历年气象资料的调查证明,花生对温度的要求很高。早熟品种全生育期要求积温一般在2600℃以上,而丰产年份的积温均在3100℃以上,中熟品种在3200℃以上;晚熟品种在3500℃以
In order to explore ways to increase peanut yield, we have systematically observed and tested the relationship between peanut and meteorological factors since 1975. In the past four years, we observed the temperature, precipitation, sunshine, ground temperature The soil moisture content of 5-20 cm was measured every five days. The observation of the fertility growth of peanut high-yielding field, the daily flowering amount and the determination of the growth rate of underground were carried out. In addition to the sowing period, watering, moisture warming agent and other auxiliary tests. A few years of observational experiments and surveys of meteorological data over the years have shown that peanuts have high requirements for temperature. Premature varieties of the whole growth period of the required temperature is generally above 2600 ℃, while the accumulated temperature in high-yielding years are above 3100 ℃, medium-mature varieties at 3200 ℃ above; late-maturing varieties at 3500 ℃ with
