別稱:磷酸氫二銨

分子式:(NH4)2HPO4

質量標準:GB 10205-2009

性狀:本品易溶于水,溶解后固形物較少。

用途:使用于各種農作物對氮磷元素的需求,尤其適合干旱少雨地施用;與尿素、硝銨可混性好,是生產多元復肥、BB肥的理想基肥。

使用說明:集中施用,或與農家肥混合施用,盡可能減少與土壤的接觸面:深施,增加與根系的接觸機會,這樣才能減少磷的化學固定和提高作物對磷肥的利用率。由于磷酸二銨的含磷量大大高于含氮量,所以無論用作底肥、種肥和追肥,要根據土壤肥瘦輪作茬口、作物品種和生長情況等,適當配合補施氮肥,使氮磷比協調,提高其肥效,保證作物生長。

作種肥時應特別注意不能與種子直接接觸:作基肥時施肥點不能離幼根幼芽太近,以免受分子中釋放的NH3灼燒。

DI-AMMONIUM PHOSPHATE(DAP)

MOLECULAR FORMULA: (NH4)2HPO4

STANDARD APPLIED: GB 10205-2009

CHARACTERITICS: It is easily solved in water and of less solid after soluted.

USAGE: It can be used for nitrogen and phosphorous supply to all kinds of plants especially in the regions with less rain. It is the best base fertilizer for multi-element compound fertilizer and BB fertilizer production.

PACKING: In 50 Kg PP woven bag with PE inner lining net each.

USING GUIDE: The principles of application of DAP: use it exclusively or use it together with farmyard manure;reduce its contact surface with the roots so as to reduce phosphorus' chemical fixation and increase the fertilizer's efficiency over the crops. As DAP's phosphorus content is much higher than its nitrogen content,so it is important to complement some nitrogen fertilizers depending on the property of the soil, the crop shifts, category of the crops and the growth of the crops whenever using it as a base fertilizer,a seed fertilizer or a complementary fertilizer in order to harmonize the proportion of nitrogen and phosphorus in the fertilizer and increase the performance of the fertilizer as much as possible.

It is important not to apply it directly to the seeds when using it as a seed fertilizer and not to apply it too closed to the seedings when using it as a base fertilizer so as to prevent the seedings from being damaged by NH3 released.
