But available P is respect of vulnerable to the effects by artificial fertilization, It reflecting the fertilization level, and can find out the available P content of the farm No 16 is higher than that of other two places through the data, which can indicate the manuring amount of the farm is larger than other two place. these three areas are all cotton growing areas, this is the reason why the cotton yield of the farm is higher than other county.

而速效磷则因为容易受人为因素的影响，能够表现出施肥量，通过数据可以看出十六团的速效磷含量比其他两个地方高出很多，可以表明兵团的施肥量要比地方的大，这三个地区都是产棉区，这也是兵团的棉花产量高于地方棉花产量的原因之一。

Low table in the conservation zone and the ball Road area, the high point of Hawaii for regular cultivation, its fertilization slightly more crop cycle, but only one year as opposed to the maintenance of a city is often green grass, crop fertilization "usage and frequency 6-7 times more."

在养护要求较低的球台区和球道区，常种植高一点的夏威夷草，其施肥喷药的周期稍长些，但是相对于常常一年只需维护一次的城市绿化草地，其施肥喷药的&用量和频率要多6至7倍&。

No evident regularity was found in the depth from 15 to 30 cm. There was an obvious accumulation of OM and TN in the top 30 cm of the fallowed soils, of which the accumulation of OM was faster than that of TN and there was more accumulation in no-tillage compared to tillage. Soils applied with inorganic and organic fertilizers had much more OM and TN at 0～5 cm and 5～15 cm depth than soils applied with only inorganic fertilizers and soils without fertilization. However, OM and TN in these treatments were less than that in fallow treatment. No significant differences in OM and TN contents were found between fertilization treatments. Only in the 5 cm of top soils, OM and TN of the soils treated with only inorganic fertilizers were more than that of CK.

长期休闲的土壤在整个耕层有明显的有机质和氮素累积，其中碳的累积快于氮的累积，免耕条件下比耕翻条件下累积量更大。0～5 cm和5～15 cm土层有机肥与无机肥配施的处理，其有机质和全氮质量分数均显著高于单施化肥处理和不施肥处理，但均低于休闲处理；15～30 cm土层各培肥处理则无明显差异；单施化肥的土壤有机质和全氮质量分数高于不施肥处理，但这种差异只在表层（0～5 cm）较显著。

The field experiments were conducted to study on the effect of different N, P2O5, K2O fertilization rate and ratio on nutrient status and tuber yield of potato in three potato production bases. According to traditional application rate, N-P2O5-K2O =300-345-375 (kg/hm2), the fertilization rate of N, P2O5, K2O was decreased to 180, 180, 225 kg/hm2, respectively.

Currently as China's accelerating development of agricultural industrialization and the increase of the agricultural production investment, the demand for chemical fertilizers increases year after year. Simultaneously as China's scientification in fertilization and fertilization ratio of the nitrogen, phosphorus, and potassium fertilizer tending to be reasonable, the chemical fertilizer demand structure will possibly change, the chemical fertilizer market environment will also change, the chemical fertilizer industry will run to the direction of high efficiency and environmentally no harm. Comparing to ordinary urea, large urea has many merits. These merits include big rime, glabrous pellet, smooth and well-mixed, not easy to crush or agglomerate in moist environment, suitable for long distance bulk transport and storage, and so on.
