为了增加花生结实率和饱荚率,提高单产,1973年在我县花生重点产区成吉、梁岔等公社,对花生进行了施用石膏的试验。共计7个试验、14个处理,每个处理面积为0.1-0.5亩,总试验面积共4.8亩,单收单晒计产。试验田为石灰性土壤,pH值8左右,水溶性钙的含量为0.044-0.077％,全氮含量为0.052-0.060％,有机质含量为0.519-0.79％,速效磷、钾缺少,土壤潜在肥力不高。一、试验结果 (一)增产显著在7个试验14个处理中均有增产,幅度为6.5-27.8％,平均增产12.8％,每亩增产花生39.2斤。一般情况下,每斤石膏增产花生1斤左右(每斤石膏6分钱左右)。肥水条件差的地增产幅度大,肥水条件好的增产幅度小。
In order to increase the peanut seedling rate and full pod rate and improve yield, in 1973, the key producing areas in our county Chenggi, Liangcha and other communes, peanut application gypsum test. A total of seven trials, 14 treatment, each processing area of 0.1-0.5 acres, the total test area of 4.8 acres, a single income single drying production. The experimental field is calcareous soil. The pH value is about 8, the content of water-soluble calcium is 0.044-0.077%, the total nitrogen content is 0.052-0.060%, the organic matter content is 0.519-0.79%, the available phosphorus and potassium are absent, and the soil potential fertility is not high . First, the test results (A) significant increase in 7 trials 14 treatments have increased production, an increase of 6.5-27.8%, with an average yield of 12.8%, 39.2 kg per acre yield peanuts. Under normal circumstances, an increase of about 1 kg of peanuts per kilogram of gypsum (about 6 cents per kilogram of gypsum). Bad water and fertilizer conditions to increase yield, good fertilizer and water conditions yield a small margin.
