以一种富含钾硅钙的微孔肥为研究对象,于2012和2013年设置了不同用量微孔肥的田间试验,分析了不同微孔肥施用量对花生产量、秸秆和籽粒养分的影响,结果表明:微孔肥可以显著提高花生产量,且花生产量随微孔肥的用量增加而增加。与CK相比,ML(600 kg/hm2)、MM(900 kg/hm2)和MH(1200 kg/hm2)处理的花生产量比不施肥增加27.0%~79.25%,比K0处理(施化肥)增加8.9%~53.2%。连续2年的养分分析显示微孔肥可以显著提高花生籽粒和秸秆的养分含量,且微孔肥的用量越高,花生秸秆和籽粒中的氮、磷、钾、硅和钙的含量越高,在2012年,微孔肥处理的秸秆氮、磷、钾、钙和硅含量分别比CK增加51.8%~80.8%、39.6%~45.2%、174.7%~216.8%、34.5%~58.2%和16.3%~34.4%,比K0分别增加46.3%~74.3%、35.2%~40.6%、34.8%~55.4%、17.5%~38.1%和10.4%~27.6%。2013年的结果与2012年基本一致。在花生籽粒中,微孔肥处理的籽粒氮、磷、钾、钙和硅含量均显著高于CK处理,但与K0相比,除了籽粒的磷含量没有显著增加之外,其余养分均显著提高。结果表明:微孔肥是提高红壤旱地花生产量和植株养分吸收能力的重要途径,且用量越高,增产效果越好。
Taking a kind of microporous fertilizer containing potassium silicate-calcium as research object, field experiments with different amounts of micropore fertilizer were set up in 2012 and 2013, and the effects of different microporous fertilizer on peanut yield, straw and grain nutrient were analyzed The results showed that micropore fertilizer can significantly increase the yield of peanut, and the yield of peanut increased with the increase of micropore fertilizer. Compared with CK, the peanut yield increased by 27.0% -79.25% in ML (600 kg / hm2), MM (900 kg / hm2) and MH (1200 kg / hm2) 8.9% ~ 53.2%. Nutrient analysis for two consecutive years showed that microporous fertilizer could significantly increase the nutrient content of peanut seeds and straw, and the higher the amount of micropore fertilizer, the higher the content of nitrogen, phosphorus, potassium, silicon and calcium in peanut straw and grain, In 2012, the contents of nitrogen, phosphorus, potassium, calcium and silicon in straw treated with micropore fertilizer increased by 51.8% -80.8%, 39.6% -45.2%, 174.7% -21.6.8%, 34.5% -58.2% and 16.3% ~ 34.4%, respectively, increased by 46.3% -74.3%, 35.2% -40.6%, 34.8% -55.4%, 17.5% -38.1% and 10.4% -27.6% respectively than K0. The results for 2013 are basically in line with 2012. Among peanut kernels, the contents of N, P, K, Ca and Si in grains treated with micropore fertilizer were significantly higher than those in CK treatments, but the contents of other nutrients were significantly increased except for the phosphorus content of K0 . The results showed that: Microporous fertilizer is an important way to increase the yield of peanut and the nutrient absorption capacity of the plant in red soil dryland. The higher the dosage, the better the yield increase.
