砂质潮土不同土体构型对花生生长和土壤养分的影响
Effects of Different Soil Configurations on Peanut Growth and Soil Nutrients in Sandy Soil
摘要
Abstract
To explore the effect of different soil configurations on peanut production and fertilizer use,the experiments of different nitrogen( 0,90,180 kg/ha) and phosphorus(0,90,135,180 kg/ha) fertilized on peanut were carried out on clip sandy loam, sandy loam, and sand soil in Qingfeng county. The results showed that application of NP fertilizer had a positive effect on development and yield of peanut. The branches of a single point and plant height of peanut with different ferti lizers at different growth stages were higher than those of CK. The branches of a single point in creased by 1 - 7 branches at early flowering stage, 1 - 10 branches at flowering stage,and 1-9 branches at full fruit and maturity stages. The plant height of peanut increased by 1 -6 cm at early flowering stage, 1-9cm at flowering stage,and 1- 7cm at full fruit and maturity stages. There were no significant differences among different soil configurations. The yield of peanut increased by 6. 01% -71. 16%,and it added 6. 0l%-67. 58% on sandy loam, 18. 83%-68. 19% on clip sandy loam,and 14. 46% -71. 16% on sand soil,respectively, with the treatment of N180P90.the best. The key of yield increase was in that the 100-peanut weight (8 -39 g) and the number of full peanuts (1 - 9 pieces/point) was improved. At the same time,the content of organic matter in cul tivated soil was improved effectively under nitrogen and phosphorus fertilizer application,and that of phosphorus and nitrogen was also increased significantly when nitrogen or phosphorus fertilizer was applied,but the content of potassium was decreased under all of the treatments. Therefore, the nitrogen and phosphorus fertilizers should be combined in sandy soil for peanut cultivation,ni trogen should be applied by stages to achieve cost savings and high efficiency,and a rational vo lume of potassium should also be applied if the condition of economy and resource was feasible.关键词
