近年来我县花生面积约在40万亩左右,单产超过225公斤。但乡(镇)村、田块之间悬殊较大,因此,如何针对大田生产,对构成产量诸因素及其之间的相互关系进行系统的分析,从而找出主攻目标,采取相应措施,对进一步提高花生产量,有着现实意义,县农业局自83年起,每年分不同地区、不同生产水平建立花生生产联络点10—14个,观察田100—425块。现选择86年有一定代表性的28个田块进行分析。 产量组成及其相互关系 86年全县实种春、夏花生面积为39.73万亩,单产232公斤,抽取分析的28个田块,品种为徐系1号,亩产变幅在171—255公斤,平均232公斤,与大田实际产量水平恰好相符,有一定的代表性。
In recent years, the peanut area in our county is about 40 million mu, yielding more than 225 kilograms. However, there is a great disparity between township (village) and land plots. Therefore, how to conduct a systematic analysis of the factors that affect yield and their interrelationships so as to find out the main target and take corresponding measures To further improve the output of peanuts, it is of practical significance. Since 2003, the County Bureau of Agriculture established 10-14 peanut production contact points and 100-425 fields of observation fields in different regions and at different levels of production each year. Now choose 86 some representative 28 plots for analysis. Yield composition and its relationship 86 county spring, summer peanut acreage of 397,300 mu, yield 232 kg, extraction and analysis of 28 plots, the variety of Xu Department No. 1, amplitude per mu in 171-255 kg , An average of 232 kg, with the field actual output level exactly the same, have a certain representation.
