Embodiment 1

[0057] On the moderately fertile plots where irrigation is guaranteed, the special fertilizer for thick-skinned melons in the present invention consists of four sets of fertilizer formulas in nutritional packages A, B, C, and D, and is used as the base fertilizer for melons and the five-leaf stage, melon sitting stage, and Top dressing during the expansion period.

[0058] (1) The nutritional package A is used as melon base fertilizer, and the fertilization rate is N 78.0kg / hm 2 +P 2 o 5 84.0kg / hm 2 +K 2 O48.0kg / hm 2 +ZnSO 4 ·7H 2 O 30.0kg / hm 2 , Before sowing or transplanting melon ridges, mix all the chemical fertilizers and sprinkle them on the ground. When ridges are formed, the fertilizers are just buried at the bottom of the ridge, 20cm away from the surface of the ridge.

[0059] (2) The nutritional package B is used as topdressing at the five-leaf stage of muskmelon, and the amount of fertilizer applied is N 52.0kg / hm 2 , 1 day before irrigation, the hole was...

Embodiment 2

[0064] Other management methods for planting soil fertility and melons are the same as in Example 1, except that nitrogen, phosphorus and potassium are all applied according to the usage and dosage designed by A, B, C, and D, but zinc, boron and calcium are lacking, and the yield of melons is 42.5t / hm 2 , the commodity rate is 77.6%, and the net income is 23086 yuan / hm 2 , the soluble sugar content is 8.44%, and the sugar-acid ratio is 17.58.

Embodiment 3

[0066] Planting soil fertility and other management methods of melons are the same as in Example 1, except that: A and B are combined and applied as base fertilizer, no fertilizer is applied at the five-leaf stage, C and D are applied as required, and the yield of melons is 44.2t / hm 2 , the commodity rate is 84.7%, and the net income is 26206 yuan / hm 2 , the soluble sugar content is 8.78%, and the sugar-acid ratio is 16.88.

Abstract

The invention provides a special fertilizer for open-field muskmelons. The special fertilizer consists of four groups of fertilizers A, B, C and D, wherein the group A fertilizer is prepared from 72.0to 84.0 kg / hm2 of N, 78.0 to 90.0 kg / hm2 of P2O5 and 36.0 to 60.0 kg / hm2 of K2O; the fertilizer in the group B comprises 48.0-56.0 kg / hm2 of N; the fertilizer in the group C comprises 72.0-84.0 kg / hm2 of N; the fertilizer of the group D comprises 48.0 to 56.0 kg / hm2 of N and 54.0 to 90.0 kg / hm2 of K2O; wherein the application amounts of N, P2O5 and K2O are based on pure nutrient amounts. Methodsof application are also provided. When the special fertilizer is applied, compared with habitual fertilization of farmers, the nitrogen fertilizer consumption is reduced by 15.2% on average, the phosphate fertilizer consumption is reduced by 9.7%, the muskmelon yield is increased by 8.4%, and the pure income is increased by 11.3%.

Description

technical field [0001] The invention belongs to the technical field of crop fertilization, and in particular relates to a special fertilizer for open field thick-skinned melons and an application method. Background technique [0002] my country is a big producer of melons, with an annual planting area of ​​about 450,000 hectares, accounting for about 37% of the world's total; output of 14 million tons, accounting for about 50% of the world's total, ranking first in the world. However, judging from the overall pattern of world melon trade, my country’s export volume in 2014 was only 42,500 tons, earning foreign exchange of 62.7863 million US dollars, and its export share only accounted for 2.73% of the world’s total, ranking 9th in the world, which is seriously inconsistent with its production status. One of the important reasons is that due to unreasonable fertilization, a large number of melons do not meet export standards or are not resistant to storage and long-distance t...
