Problems solved by technology

However, due to the significant differences in the properties of various crops, the model parameters cannot be used as substitutes. Moreover, there are many varieties of radishes, which are divided into spring, summer, autumn and winter radishes according to the seasons, and the planting area is vast

Embodiment 1

[0073] Embodiment 1 field verification test

[0074] The experiment was carried out in Tianjin, Shandong, and Beijing in the spring and autumn of 2018. Four experimental sites were arranged in each region in the spring and autumn, and a total of 24 field experiments were conducted in three regions in the two seasons.

[0075] Before the radish is planted, the planting information survey is carried out on each experimental plot to obtain information such as the radish yield, fertilization amount, and fertilization method of the farmers in previous years, and determine the target yield of radish and the level of basic soil nutrient supply.

[0076] Through the recommended fertilization method (NE), the yield response and the amount of nitrogen, phosphorus and potassium fertilizers were calculated (see Table 5), and farmers' customary fertilization treatment (FP) and soil testing and fertilization treatment (ST) were set as controls.

[0077] The area of ​​each plot is guaranteed...

Abstract

The invention relates to a recommended fertilizer application method of radishes. The method comprises the following steps of determining the target yield of radishes in season according to the past radish yield level in existing land; (2) determining the basic nutrition supply level of the soil of the existing land; (3) calculating the yield reaction of the existing land according to multi-year multi-point factor reduction tests; or estimating the yield reaction of the fertilization according to the basic nutrition supply level of the soil of the existing land and a yield reaction coefficient; (4) performing simulation by using a QUEFTS model to obtain the best nutrition demand of the radishes; calculating the consumption of N, P and K fertilizers required by the radishes to reach the target yield by combining the target yield, the yield reaction, the soil basic nutrition supply level, the agronomic efficiency, the preceding crop straw turnover and in-season crop nutrient residue balance factors. The method is applicable to the fertilization recommendation of the radishes in the land with different sizes; the application can be realized under the conditions of test with the soil or test without the soil; the characteristics of high timeliness, easy mastering, wide application and the like are realized.

Description

technical field [0001] The invention relates to a recommended fertilization method for radish, which belongs to the field of agricultural resources and environment. Background technique [0002] my country is one of the birthplaces of radish, with a cultivation history of more than 2,700 years. Radish is a cruciferous plant. It is a root vegetable whose taproot expands to form a fleshy root as an edible organ. It is loved by people all over the world because of its rich nutritional value and super strong health effects. Radish is the second largest category of vegetables in my country. It is cultivated in all parts of the north and south, and occupies an important position in the production and consumption of vegetables in our country. [0003] Fertilization is one of the important technical measures to ensure high-yield and high-quality radish. However, at present, farmers in radish production mostly follow traditional experience in fertilization. Vegetable farmers blindly...
