Embodiment 1
[0071] Example 1: Special controlled-release fertilizer for betel nut
[0072] Mix the raw materials with a particle size of 2-5 mm according to the following ratio to obtain the special controlled-release fertilizer for betel nut:
[0073] Release period is 80 parts of 4% film-forming coated urea of 80 days;
[0074] Release period is 100 parts of 5% film-forming coated urea of 150 days;
[0075] 200 parts of urea;
[0076] 90 parts of diammonium phosphate;
[0077] 400 parts of potassium sulfate;
[0078] 10 parts of borax;
[0079] In the special controlled-release fertilizer for betel nuts, the weight ratio of nitrogen, phosphorus pentoxide and potassium oxide is 1:0.4:1.2.
[0080] The curve diagram of the nutrient release law of the controlled-release fertilizer and the nutrient absorption law of betel nut is as follows figure 1 shown. It can be seen from the figure that the nutrients of the controlled-release special fertilizer basically coincide with the reg...

[0081] Example 2: special controlled-release fertilizer for betel nut
[0082] Mix the raw materials with a particle size of 2-5 mm according to the following ratio to obtain the special controlled-release fertilizer for betel nut:
[0083] Release period is 70 parts of 4% film-forming coated urea in 60 days;
[0084] Release period is 120 parts of 5% reaction film-forming coated urea of 120 days;
[0085] 200 parts of urea;
[0086] 100 parts of diammonium phosphate;
[0087] 420 parts of potassium chloride;
[0088] 15 parts of borax;
[0089] In the special controlled-release fertilizer for betel nuts, the weight ratio of nitrogen, phosphorus pentoxide and potassium oxide is 1:0.5:1.4.
[0090] The nutrient absorption curve graph of the controlled-release fertilizer and figure 1 There is no substantive difference and will not be repeated here.

Abstract
The invention discloses an areca catechu controlled-release fertilizer and a preparation method thereof. The controlled-release fertilizer is prepared by compounding ingredients, such as reactive film forming and enveloping urea with enveloping quantity of 4%and enveloping quantity of 5% (at different nutrient release periods), urea, diammonium phosphate, potassium sulfate and borax. The special nutrition-synchronized controlled-release fertilizer for areca catechu, disclosed by the invention, is compounded according to the characteristics, nutrient demand law and required nutrient elements of the normal growth, development and cultivation of areca catechu, nutrients required by areca catechu can be supplied continuously and synchronously, the needs of three key elements, namely nitrogen, phosphorus and potassium, and a nutrient element, namely boron, in a yearly growth period of areca catechu are met, and the fertility is more lasting, so that the plant body resistance is effectively adjusted, the diseases are reduced, the yield is increased, the quality of crops is greatly improved, and the mouth feel of areca catechu is good; the problem of high cost caused by the fact that the controlled-release fertilizer is used alone is solved; and meanwhile, the fertilization times can be decreased by 1-2 times, so that the labor intensity is reduced.
Description
technical field [0001] The invention belongs to the technical field of slow / controlled release fertilizers, and relates to a betel nut controlled release fertilizer and a preparation method thereof. Background technique [0002] Betel nut (Areca cathecu L.) belongs to the perennial evergreen tree of the palm family. Its fruit is oval, with a large hilum and hard quality. It is one of the four major southern medicines in my country. In addition, its fresh fruit is a hobby food, and its peel is also a raw material for the textile industry. In recent years, due to the strong resistance, wide adaptability, extensive management, low planting cost and good economic benefits of betel nut, the betel nut planting industry has developed rapidly and the planting area has increased significantly. At present, China is the second producer of betel nuts in the world, and the output of areca nuts in Hainan accounts for about 99% of the output in mainland China. [0003] The betel nut tree...
