[0017] A preparation method of a water-retaining slow-release fertilizer for yew, comprising the following steps:
[0018] (1) Crush attapulgite, carnallite and hectorite into 60-80 mesh powder, and then put them into a stirring tank together with tricalcium phosphate, potassium dihydrogen phosphate and carboxymethyl starch at 300-400r / min Dry mix for 8-10min under the speed of rotation to obtain the premix;
[0022] A water-retaining slow-release fertilizer for yew, prepared by the following raw materials in parts by weight: 11 parts of attapulgite, 8 parts of zinc sulfate, 9 parts of tricalcium phosphate, 5.5 parts of ammonium molybdate, diphosphate 7 parts of potassium hydrogen, 6 parts of urea, 7 parts of ammonium chloride, 3.5 parts of epichlorohydrin, 6 parts of carboxymethyl starch, 4 parts of diammonium phosphate, 5 parts of carnallite, 25 parts of cellulose grafted acrylate, 20 parts of starch grafted acrylamide.
[0023] The preparation method is the same as in Example 1.
Embodiment 3
[0025] A water-retaining slow-release fertilizer for yew, prepared by the following raw materials in parts by weight: 12 parts of attapulgite, 9 parts of zinc sulfate, 10 parts of tricalcium phosphate, 6 parts of ammonium molybdate, diphosphate 8 parts of potassium hydrogen, 7 parts of urea, 8 parts of ammonium chloride, 4 parts of epichlorohydrin, 7 parts of carboxymethyl starch, 5 parts of diammonium phosphate, 6 parts of carnallite, 30 parts of cellulose grafted acrylate, 25 parts of starch grafted acrylamide.
[0026] The preparation method is the same as in Example 1.
[0027] In order to further illustrate the application value of the present invention, select 1000 yew saplings with similar growth conditions, be divided into 3 groups of experimental groups and 1 group of control groups on average, and 3 groups of experimental groups use the slow-release method in the embodiment of the present invention 1-3 respectively. Fertilizer, the control group uses common fertiliz...

field of invention [0001] The invention relates to a fertilizer, in particular to a water-retaining slow-release fertilizer for yew and a preparation method thereof. Background technique [0002] Yew, also known as yew, is a plant in the genusTaxus. Yew is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It is recognized as a rare and natural anti-cancer plant on the verge of extinction in the world. It is an ancient relic tree species left over from Quaternary glaciers. history. Due to the slow growth rate and poor regeneration ability of yew under natural conditions, there has not been a large-scale yew raw material forest base in the world for a long time. In 1994, yew was designated as a first-class rare and endangered protected plant by my country, and was also called a "national treasure" by 42 countries with yew in the world. The United Nations also explicitly prohibited logging. It is a veritable "plant panda". [0003] Yew i...
