别称:磷酸氢二铵

分子式:(NH4)2HPO4

质量标准:GB 10205-2009

实博体育app 性状:本品易溶于水,溶解后固形物较少。

用途:使用于各种农作物对氮磷元素的需求,尤其适合干旱少雨地施用;与尿素、硝铵可混性好,是生产多元复肥、BB肥的理想基肥。

使用说明:集中施用,或与农家肥混合施用,尽可能减少与土壤的接触面:深施,增加与根系的接触机会,这样才能减少磷的化学固定和提高作物对磷肥的利用率。由于磷酸二铵的含磷量大大高于含氮量,所以无论用作底肥、种肥和追肥,要根据土壤肥瘦轮作茬口、作物品种和生长情况等,适当配合补施氮肥,使氮磷比协调,提高其肥效,保证作物生长。

作种肥时应特别注意不能与种子直接接触:作基肥时施肥点不能离幼根幼芽太近,以免受分子中释放的NH3灼烧。

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.

实博体育app PACKING: In 50 Kg PP woven bag with PE inner lining net each.

实博体育app 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.
