Embodiment 1

[0031] Embodiment 1 Broccoli Nitrogen Phosphorus Potassium Different Application Rate Test

[0032] ⑴Experimental Design This experiment was carried out in a certain village in 2011, with a total of 15 treatments, 14 (3414 experiments) + 1 (local fertilization habits), with 3 repetitions, a total of 45 experimental plots, each with an area of 30m 2 , 120 broccoli plants per plot, randomly arranged in each plot; the broccoli variety is early-maturing and excellent; the basic physical and chemical properties of the tested soil are pH6.53, and the organic matter is 29.7g·kg -1 , the alkaline hydrolysis nitrogen is 118mg·kg -1 , available phosphorus 15.7mg·kg -1 , available potassium 180mg·kg -1 ;N,P 2 o 5 、K 2 The 2 levels of O are respectively set to 300kg·hm -2 、120kg·hm -2 、180kg·hm -2 ; Local customary fertilization treatment N, P 2 o 5 、K 2 O is 480kg·hm respectively -2 、240kg·hm -2 、240kg·hm -2 , the fertilizer application is: 30% nitrogen fertilizer, 30% pot...

Embodiment 2

[0039] Embodiment 2 Comparison of the influence of different fertilization methods on broccoli yield

[0040] 1. Manufacture of special formula fertilizer for broccoli

[0041] On the basis of the test results in 2011, in 2012, the test and research on the special formula fertilizer for broccoli was carried out. The basic fertilizers include urea, superphosphate, potassium chloride, borax imported from the United States and straw gasification residue, and the main components are nitrogen, phosphorus and potassium. Accounting for 90% of the total component mass fraction, and N:P 2 o 5 :K 2 The mass ratio of O is 3:1:2; the subcomponents account for 10% of the total component mass fraction, of which borax accounts for 0.2% of the total component, and straw gasification residue accounts for 9.8% of the total component. This special formula Fertilizer production methods are as follows:

[0042] (1) Select basic fertilizers urea, superphosphate and potassium chloride respective...

Embodiment 3

[0061] Embodiment 3 A special formula fertilizer for broccoli under medium soil fertility, consisting of basic fertilizers urea, ammonium phosphate, and potassium chloride, nitrogen, phosphorus, and potassium account for 90% of the total component mass fraction, and N:P 2 o 5 :K 2 The mass ratio of O is 3:1:2; the subcomponents account for 10% of the total component mass fraction, of which borax accounts for 0.2% of the total component, and straw gasification residue accounts for 9.8% of the total component. The production method And application method is substantially the same as embodiment 1.

Abstract

The invention provides a special formulated fertilizer for broccoli at medium soil productivity condition, which can improve the yield and the quality of broccoli, can be used as a base fertilizer and an additional fertilizer and provide nutrition in the whole growth duration. The special formulated fertilizer comprises principal components of N, P and K, as well as secondary component borax and straw gasification residues, wherein the mass ratio of N to P2O5 to K2O is (3-4.5): (1-1.5): (2-3), and the principal components account for 90-95% of the mass of the total components. The straw gasification residues contain a quantity of organic matters due to incomplete combustion, so that due to the application of the special formulated fertilizer in which the straw gasification residues are added, the fertilizer production cost is greatly saved, the soil productivity is fertilized, and the fertilizer utilization rate and the crop quality are enhanced.

Description

technical field [0001] The invention belongs to the technical field of fertilizer formulas, and in particular relates to a special formula fertilizer for broccoli under moderate soil fertility conditions. Background technique [0002] The perennial broccoli cultivation area in Zhejiang Province has reached (0.8-1.0) million hectares, accounting for more than 70% of the total area of ​​the country, and Taizhou broccoli has accounted for about 3 / 5 of the total cultivation area of ​​Zhejiang Province, mainly concentrated in Linhai , Sanmen, Luqiao, Jiaojiang and Wenling and other areas. Due to the relatively high market price of broccoli, farmers blindly pursue high yields, and the phenomenon of partial application or heavy application of high-concentration compound fertilizers is very serious, especially the high-concentration compound fertilizers produced abroad are favored by farmers, resulting in higher planting costs for broccoli. In recent years, affected by risk factors...
