In the process of agricultural production, fertilizer application is essential, but what are the important points of fertilizer application? The ten major points of attention should be paid to the analysis of agricultural fertilizer:

　　1、未腐熟的農(nóng)家肥和餅肥不宜直接使用。應(yīng)先將農(nóng)家肥和餅肥充分堆漚腐熟，經(jīng)高溫消毒或藥劑處理后再使用。

　　1, raw manure and fertilizer is not used directly. We should first fully cake manure and composting, after high temperature disinfection or chemical treatment before use.

　　2、含氯的化肥不宜使用在鹽堿地和忌氯作物上。忌氯作物有煙草、水果、甜菜、薯類、西瓜等。

　　2, chlorine fertilizer should not be used in saline alkali soil and avoid chlorine crops. Bogey chlorine crops, tobacco, fruit, sugar beet, potato, watermelon and so on.

　　3、氮素化肥不宜淺施或澆水前施用。氮素化肥施入土壤后一般要轉(zhuǎn)化為銨態(tài)氮，容易隨水流失或受光熱作用而揮發(fā)，失去肥效。

　　3, nitrogen fertilizer should not be applied before water or before watering. When nitrogen fertilizer is applied to the soil, it is generally converted to ammonium nitrogen, which is easy to evaporate with water loss or be affected by light and heat, and lose fertilizer effect.

　　4、銨態(tài)氮肥不宜與草木灰等堿性肥料混合使用。

　　4, ammonium nitrogen fertilizer should not be mixed with plant ash and other basic fertilizers.

　　5、氮肥不宜多施于豆科作物上。豆科作物根部都有固氮根瘤菌，過多施用氮素肥料，不僅會造成浪費，還會使作物貪青晚熟，影響產(chǎn)量。

　　5, nitrogen fertilizer should not be applied to legume crops. The roots of leguminous crops have rhizobia, excessive application of nitrogen fertilizer, not only will be wasted, will make the crop yield of late maturing.

　　6、磷肥不宜分散使用。磷肥中的磷元素容易被土壤吸收固定，失去肥效，應(yīng)先將磷肥與積肥混合堆漚一段時間，再溝施或穴施于作物根系附近。

　　6, phosphorus fertilizer should not be dispersed. Phosphorus in phosphate fertilizer easily absorbed by soil fixed, loss of fertilizer, phosphate fertilizer and manure should be mixed compost for a period of time, and then to the hole near the crop root or furrow.

　　7、含磷量較高的肥料不宜多用于蔬菜。

　　7, high phosphorus content fertilizer should not be used for vegetables.

　　8、鉀肥不宜在作物生長后期使用。

　　8, potassium fertilizer should not be used in the late growth of crops.

　　9、稀土肥料不宜直接施于土壤中。

　　9, rare earth fertilizer should not be directly applied to the soil.

　　10、不宜不分作物品種和生育期濫施肥料。

　　10, is not divided into crop varieties and growth period of abuse of fertilizer.
