  deep placement
Deep placement of urea supergranules reduced the negative impact of N fertilizer on blue-green algal populations.
      
Deep placement of N avoided the proliferation of ostracods and dipteran larvae.
      
An excessively deep placement of the catheter tip was seen in 5 of the controls, but in none of the TEE group.
      
However, grain yields were significantly higher with deep placement of nitrogen than with split application of the fertilizer.
      
Other promising alternative practices are use of N-efficient rice varieties, hand or machine deep placement of urea supergranules, and use of slow release N fertilizers.

It is suggested generally that small quantity,repeat dressing of P in CSP and conbining top dressing with deeper ones in the soil are more efficient.Because in soils P becomes fixed easily, and moves rather slowly and runs unavailable in some soils rapidly.The more the P-fertilizer be dressed-to soil layers where roots densely distributed the better the nutrients to the plant will be. P-fertilization not only increases the yield of alfalfa but also(improves the quality of it in lower- P soils.While it is not...

P-fertilization not only increases the yield of alfalfa but also(improves the quality of it in lower- P soils.While it is not natable in high-P soils.However,lots of people hoid that it may be unwise to cancel the P-fertilization for high-P soils.P-fertilizers should also be applied to high-P soils at a maintenance level nevertheless.

由于磷容易被土壤固定,不易移动,利用率很快下降,故一般认为以高效过磷酸钙为磷源,少量多次、表面和深层施肥相结合为宜。施于根系较密集处,能较多地提供植物磷营养。在低磷地区,磷肥不仅能提高产量,而且能改善品质,但在高磷地区效果不明显。尽管如此,仍有不少人认为不施磷肥是不明智之举,建议施用维持量为宜。

The study on the main ecological effects of wheat root systems was carried outfrom 1988 to 1992.The results showed that 1. The relative soil water content suitable tothe development of root systems was 70%to80%. When it was below 60%,the growth ofroot systems slowed down significantly;when below 30%,the root systems stopped grow-ing or died,2.The root systems were highly sensitive to the fluctuation of temperaturewhich affected the growth rate of root systems. 3.The applying of fertilizer on the surfacelayer...

通过小麦根系对土壤水分、施肥深度和气温变化等生态效应的研究表明:小麦根系生长的适宜土壤相对含水量为70%~80%,低于60%,明显受抑制,在小麦抽穗开花期,根系生理活性对土壤水分的反应最明显;气温变化通过植株生长,会引起根系迅速地反应出来。根系对秋、冬季和春季温度变化的反应有显著区别;土层施肥可使根系早期生长健壮,利于壮苗,深层施肥可促使下层根量增多。用 ̄(32)P示踪试验证明,在一些分蘖死亡的情况下,其基部着生的根仍继续保持着生活能力,而且对整个植株同样起着根的应有作用。
