Embodiment 1

[0023] In 2006, a long-season tomato overwintering cultivation experiment was carried out in a solar greenhouse in Jiyang County, Shandong Province. The solar greenhouse area is 667m 2 ; Tomato seedlings were grown on July 25, 2006, planted on August 24, and seedlings were pulled on June 15, 2007. The tomato variety for testing was Zhongza No. 9; fertilizer management was segmented according to the law of nutrient demand in different growth stages management, and other management as usual.

[0024] (1) Determining the amount of nitrogen and phosphorus fertilizer: according to the cultivation experience, the target output of tomato is set to be 15000kg / mu, and the total amount of nitrogen fertilizer = 15000kg / mu × 0.003 = 45kg / mu, the total amount of phosphate fertilizer = 45kg / mu × 0.5 = 22.5kg / mu .

[0025] (2) Base fertilizer application: Apply 2000kg of sterilized chicken manure; Nitrogen fertilizer base application rate=45kg / mu×0.4=18kg / mu, phosphorus fertilizer base appl...

Embodiment 2

[0038] In 2008, a tomato overwintering long-season cultivation experiment was carried out in a solar greenhouse in Shouguang City, Shandong Province. The solar greenhouse area was 800m2; tomato seedlings were raised on August 1, 2008, planted on August 29, and seedlings were pulled on June 20, 2009. The tested tomato variety is Chaoyan Fenwang; fertilizer management is carried out in stages according to the law of nutrient demand in different growth stages, and other management is as usual.

[0039](1) Determining the amount of nitrogen and phosphorus fertilizers: setting the tomato target yield according to the cultivation experience is 18000kg / mu, determining the total amount of nitrogen fertilizer=18000kg / mu×0.003=54kg / mu, and the total amount of phosphate fertilizer=54kg / mu×0.5=27kg / mu.

[0040] (2) Base fertilizer application: apply 3000kg of sterilized chicken manure; nitrogen fertilizer base application amount=54kg / mu×0.4=21.6kg / mu, phosphorus fertilizer base application...

Abstract

The invention relates to a fertilization method for protected tomato overwinter long-season cultivation. The fertilization method of the invention is to fertilize stepwise and accurately according to the characteristics of nitrogen and potassium needs of tomatoes in different growth periods in long-season cultivation. The method comprises: applying a basic fertilizer (nitrogen fertilizer: potassium fertilizer=1.0:1.5); applying a fertilizer in a fruit-setting period (nitrogen fertilizer: potassium fertilizer=1.0:1.0); applying a fertilizer in an initial harvesting period (nitrogen fertilizer: potassium fertilizer=1.0:1.2); applying a fertilizer in a middle harvesting period (nitrogen fertilizer: potassium fertilizer=1.0:1.4); and applying a fertilizer in the late harvesting period (nitrogen fertilizer: potassium fertilizer=1.0:1.2). The fertilization method is in accordance with the characteristics of the nutrient needs of the tomatoes in long-season cultivation, can effectively promote the balance between the vegetative growth and reproductive growth of the tomatoes, solves the problem of low fruit setting capacity of the tomatoes in long-season cultivation, improves tomato yield and fruit quality, reduces fertilizer investment, improves the production efficiency of the fertilizer effectively, and realizes cost conservation and synergistic effect in a real sense.

Description

technical field [0001] The invention relates to a fertilization method for facility tomato long-season cultivation, in particular to a segmented fertilization management method based on the demand rules of nutrients in different growth stages of tomato, and belongs to the technical field of agricultural cultivation. Background technique [0002] Tomato is a worldwide vegetable crop and one of the important crops under protected cultivation. It plays an important role in people's daily life. At present, the tomato planting area in the world is about 2.7×10 7 hm 2 , the output accounts for 17% of the total vegetable output. In the Netherlands, where facility horticulture is highly developed, the tomato production area accounts for 1 / 3 of the greenhouse vegetable area, and the output per unit area of ​​tomato is as high as 52kg / m 2 . In my country's protected vegetable cultivation, tomato is the main vegetable species. However, due to the backward cultivation technology such ...
