摘要

为研究有机肥培肥复垦土壤过程中磷的有效性如何变化、不同有机肥在什么施磷水平下能使作物取得最大生产效率以及合理培肥土壤，依托采煤塌陷定位培肥试验基地（山西省孝义市偏城村），在4个磷水平下（0，25，50，100 kg/hm2）研究不同肥料（鸡粪、猪粪、牛粪和化肥）对玉米产量及土壤速效磷含量的动态变化。经过2年的田间试验，结果表明：（1）施用有机肥和化肥均能显著提高玉米籽粒产量，随着施磷量的增加，玉米籽粒产量呈先增加后基本不变的趋势，通过构建2年磷肥效应方程发现，化肥、鸡粪、猪粪和牛粪处理的最佳施磷量范围分别为67.54~83.02，24.91~38.65，26.10~29.26，50.33~58.38 kg/hm2，可见，3种有机肥推荐施磷量均小于化肥处理；（2）玉米吸磷量和磷肥利用率在各施磷水平下均表现为鸡粪 ≥猪粪>牛粪>化肥。玉米吸磷量随施磷水平的增加呈先增后基本不变的趋势，磷肥当季回收率表现为随施磷水平的增加呈下降趋势；（3）连续施肥2年后，不同施肥处理在采煤塌陷区复垦土壤上影响的土壤有效磷深度不同。其中，化肥处理在50，100 kg/hm2磷水平下显著提高0—60 cm土层Olsen—P含量；鸡粪处理在50 kg/hm2磷水平下显著提高0—40 cm土层Olsen—P含量，而100 kg/hm2磷水平下显著提高Olsen—P含量到60 cm土层；猪粪处理在50，100 kg/hm2磷水平下显著提高0—40 cm土层Olsen—P含量；牛粪处理仅对表层Olsen—P含量有影响。总之，不同有机肥处理之间对作物生长和土壤Olsen—P含量的影响均表现为鸡粪 ≥猪粪>牛粪，且不同有机肥对于新复垦土壤的推荐施肥量不同，鸡粪和猪粪的推荐施磷量最少，其次为牛粪处理。

Abstract

This study aimed to study how phosphorus availability changes during soil reclamation with organic fertilizer and at what level of phosphorus application can different organic fertilizer make crops achieve maximum productivity and enriching the soil resonable. For these reasons

a two-year experiment was conducted at the coal mining collapse test base (Piancheng Village

Xiaoyi city

Shanxi Province)

with setting four fertilization types (chicken manure

pig manure

cow manure and fertilizer) and four phosphorus levels of 0

50 and 100 kg/hm2 (pure phosphorus). The results showed that:(1) Different fertilization treatments could significantly increase the yield of corn grain yield. With the increase of phosphorus application

the corn grain yield increased first and then remained unchanged. Through constructing the two-year phosphorus fertilizer effect equation

it was found that the optimal phosphorus application ranges of chemical fertilizer

chicken manure

pig manure and cow manure treatment were 67.54~83.02

24.91~38.65

26.10~29.26 and 50.33~58.38 kg/hm2

it can be seen that the optimal phosphous application of three organic fertilizer is less than chemical fertilizer treatment. (2) The phosphorus uptake and apparent use efficiency of phosphate fertilizer of maize showed that chicken manure ≥ pig manure>cow manure. The phosphorus uptake of maize increased first and then decreased with the increase of the phosphorus application levels

and the recovery rate of phosphate fertilizer decreased. (3) After continuous fertilization for two years

the depth of soil available P influenced by different fertilization treatments on the reclaimed soil was different. The content of Olsen—P in the 0—60 cm soil layer was significantly increased by the chemical treatment at the dosages of 50 and 100 kg/hm2 phosphorus. However

the content of Olsen—P in 0—40 cm soil layer was significantly increased by chicken manure treatment at the dosages of 50 kg/hm2 phosphorus

the content of Olsen—P in 0—60 cm soil layer was significantly increased by chicken manure treatment the dosages of 100 kg/hm2 phosphorus. The pig manure treatment at the dosages of 50 and 100 kg/hm2 phosphorus only significantly increased the content of Olsen—P in the 0—40 cm soil layer

and cow manure treatment only increased the content of Olsen—P in the surface layer. In a word

both the effects of different organic fertilizers on crop growth and soil Olsen—P content showed chicken manure ≥ pig manure>cow manure. In addition

the different amounts of phosphorus was recommended to the newly reclaimed soil for different organic fertilizers

among which chicken manure and pig manure were least

followed by cow manure.
