Problems solved by technology

[0002] In recent years, with people's blind pursuit of high yield and indiscriminate use of fertilizers, not only the waste of resources has been caused, but also the proportion of soil nutrients in the facilities has been seriously out of balance.

example 1

[0018] Example 1. Take melon planting in a certain area as an example, the planting area is 1.0 mu

[0019] (1) Detection of nutrients in the soil

[0020] ①Sampling: After the previous crops are harvested, choose a plot with a plot area of ​​1.0 mu. According to the S-shaped route, according to the principle of random, equal amount, and multi-point mixing, each sample has 25 sampling points with a depth of 0-25cm, and then take a soil sample of about 1kg according to the "quarter method", and finally use GPS to locate the longitude and latitude of the sample, and fill in the sampling survey form;

Abstract

The invention provides a method of formula fertilization of muskmelon after soil testing. The method is based on the fertilizer demand characteristics of muskmelon and comprises the following three steps: detection analysis of soil nutrients, calculation of a fertilizing amount and fertilization. According to the invention, scientific and reasonable adjustment of a ratio of N to P to K and coordination of the proportions of soil nutrients are realized fully based on the growth and development rules of muskmelon; thus, the utilization rate of a fertilizer is improved by more than 10%, soil fertility can be substantially fostered, nutrient loss, proportional unbalance, salination and the like can be obviously reduced, the output of muskmelon can be increased, and the method is applicable to high-yield cultivation of muskmelon.

Description

Technical field [0001] The invention relates to a soil testing formula fertilization method, in particular to a formula fertilization method for fertilizing according to the fertilizer-requiring characteristics of melons and soil nutrients. Background technique [0002] In recent years, as people blindly pursue high yields and use fertilizers indiscriminately, they have not only caused a waste of resources, but also caused a serious imbalance in the proportion of soil nutrients in the facilities. In view of this, while ensuring crop yields, reasonable formula fertilization methods should be adopted to reduce the production cost of fertilization, improve the economic benefits of agricultural production, and maintain the sustainable and stable development of agriculture. Fertilization should also pay attention to fertilization and environmental protection. At the same time, it is hoped that the long-term use of melon formula fertilization technology can reduce the application of ch...
