Embodiment 1

[0029] Example 1 Application test of watermelon special formula fertilizer

[0030] (1) Experimental Design The experiment was carried out in Shunyi Greenhouse from March to June 2010. The soil organic matter in the test field (0-20 cm) is 17.17 g / kg, available silicon is 142.52 mg / kg, pH is 6.32, nitrate nitrogen is 84.40 mg / kg, available phosphorus (P) is 93.08 mg / kg, available potassium (K) 149.34 mg / kg. The area of ​​the greenhouse is 0.7 mu, and the tested watermelon variety is early-maturing small "Early Spring Hongyu". There are 2 rows in each ridge, the distance between plants and rows is 50 cm, and the distance between ridges is 100 cm, and 15 watermelons are planted in each row. The test set 5 fertilization treatments, each treatment area 1.5m (width) × 7m (length) = 10.5m 2 .

[0031] The basic fertilizer composition of each fertilization treatment is shown in Table 1. The fertilizers of each treatment (Na1, Na2, Ca1, and Ca2 represent different fertilization le...

Embodiment 2

[0053] Embodiment 2 A special formula fertilizer for watermelon is composed of basic fertilizer urea, diammonium, potassium sulfate, sodium silicate, and contains N:P 2 o 5 :K 2 O:SiO 2 The mass ratio is 2:1:1.5:2.

[0054] The production method of this special formula fertilizer for watermelon is as follows:

[0055] (1) Select the basic fertilizers urea, diammonium, potassium sulfate and sodium silicate containing nitrogen, phosphorus, potassium and silicon respectively;

[0056] (2) The amount of the above-mentioned basic fertilizers required for the production of 100 tons of special formula fertilizer for watermelons is a, b, c, d in sequence, and is solved according to the following equations:

[0057]

[0058] The solution is a=12.1 tons, b=19.5 tons, c=15.5 tons, d=52.9 tons

[0059] (3) Weigh the required various basic fertilizers according to the above weight, and make the special formula fertilizer for watermelon through the processes of crushing, mixing, gr...

Embodiment 3

[0062] Embodiment 3 A special formula fertilizer for watermelons is composed of basic fertilizer urea, triple superphosphate, potassium nitrate, calcium silicate, and contains N:P 2 o 5 :K 2 O:SiO 2 The mass ratio is 1:0.5:1:2.

[0063] Its production and application methods are basically the same as in Example 2.

Abstract

The invention relates to a watermelon special formula fertilizer containing a silicon ingredient, aiming to solve the technical problems of poor watermelon quality and low yield under the conventional fertilizing mode. The watermelon special formula fertilizer comprises nitrogen, phosphor, kalium and silicon, wherein the mass ratio of N to P2O5 to K2O to SiO2 IS 1-2:0.5-1:1-1.5:2-4. The nutrition proportion of the watermelon special formula fertilizer can meet the growing requirement of the watermelon; the watermelon grows robustly and has few plant diseases and insect pests; the soluble sugar content, the VC content and the soluble solid content of the watermelon fruits are remarkably increased; the watermelon has thin peel and crisp flesh; the single melon weight and the yield of the watermelon are remarkably improved; the watermelon special formula fertilizer is a novel multifunctional fertilizer which is incomparable with other chemical fertilizers, and the silicon ingredient of the watermelon special formula fertilizer is a quality and health-care element, and can promote balanced absorption of a watermelon plant to the nitrogen, the phosphor and the kalium so as to improve the quality and yield of the watermelon fruits.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special formula fertilizer suitable for early-maturing watermelons in greenhouses. Background technique [0002] Watermelon is one of the top ten fruits in the world, and my country is the largest watermelon producer in the world, with planting area and total output accounting for more than 45% of the world's total. However, the research on watermelon fertilization in my country started relatively late, the quality of watermelon is relatively poor, and the economic benefits of planting are difficult to satisfy. With my country's accession to WTO, the watermelon consumer market is facing international competition, and it is very urgent to improve the quality of watermelon. At the same time, with the improvement of living standards and the diversification of fruit varieties, domestic consumers have higher and higher requirements for the quality of melons and fruits. Since the reform ...
