Embodiment Construction

[0026] The present invention will be further described below in conjunction with examples and comparative examples, but not limited thereto.

[0027] The application effect of above embodiment 1-2 and comparative example is as follows:

[0028] A special formula fertilizer for pineapple, characterized in that: by weight, its raw material components are N:P 2 o 5 :K 2 O=18:10:20; 160 parts of polyurethane-coated urea with 5% coating amount, 80 parts of urea, 80 parts of polypeptide urea, 80 parts of urea-formaldehyde fertilizer, 150 parts of superphosphate, 400 parts of potassium sulfate, and 50 parts of humic acid , 10 parts of boron fertilizer, 40 parts of magnesium sulfate.

[0029] The polyurethane-coated urea with a coating amount of 5% means that the quality of the coating layer is 5% of the total mass.

[0030] The urea-formaldehyde fertilizer refers to slow-release nitrogen fertilizer obtained by reacting urea and formaldehyde.

[0031] Described humic acid is liqu...

Abstract

The invention relates to a formula fertilizer special for jackfruits. The formula fertilizer is characterized in that raw materials comprise the following components in parts by weight: N, P2O5, K2O, 160 parts of polyurethane coated urea with the coating quantity of 5%, 80 parts of urea, 80 parts of polypeptide urea, 80 parts of urea-formaldehyde fertilizer, 150 parts of calcium superphosphate, 400 parts of potassium sulfate, 50 parts of humic acid, 10 parts of boron fertilizer and 40 parts of magnesium sulfate, wherein the ratio of N to P2O5 to K2O is 18:10:20. The formula fertilizer has the beneficial effects as follows: 1, nutrients are reasonably formulated; 2, slow release and controlled release are combined; 3, organic and inorganic combination is adopted to achieve the effects of increasing yield and modifying soil; 4, the stress resistance of crops is improved; 5, the formula fertilizer has a good yield-increasing effect, and saves time and labor.

Description

technical field [0001] The invention relates to a special formula fertilizer for jackfruit. Background technique [0002] jackfruit (Artocarpusheterophyllus Lam.)
