Embodiment 1

[0021] A special fertilizer for the integration of water and fertilizer in strawberry flowering and fruiting period, the special fertilizer is a high-potassium water-soluble fertilizer with a total nutrient content of 54%. The high-potassium water-soluble fertilizer is a water-soluble fertilizer with nitrogen, phosphorus and potassium contents of 20-10-24.

[0022] Above-mentioned high-potassium type water-soluble fertilizer comprises the component of following percentage by weight:

[0023] Ammonium dihydrogen phosphate 16.5%, potassium sulfate 27%, urea 33%, potassium nitrate 21.28%, calcium magnesium nitrate 2%, chelated zinc 0.05%, chelated boron 0.05%, chelated molybdenum 0.08%, chelated Combined manganese 0.04% and other trace elements.

[0024] The above-mentioned high-potassium water-soluble fertilizers are prepared immediately after use, so as to avoid long-term storage and agglomeration. The preparation method is: weigh each component of the fertilizer according to...

Embodiment 2

[0031] Embodiment 2: basically the same as Embodiment 1, the difference is:

[0032] From September 2014 to May 2015, the special fertilizer in Example 1 was used in the strawberry base of the Houbailiang Seed Field in Jurong City. Due to the insufficient fertilization of the strawberry field, the frequency of topdressing was relatively high, and a total of Top dressing 9 times, every hm 2 Use 45 kg of fertilizer.

Embodiment 3

[0033] Embodiment 3: basically the same as Embodiment 1, the difference is:

[0034] From September 2014 to May 2015 and from September 2015 to April 2016, in two years at the Yuntu Strawberry Professional Cooperative in Baitu Town, Jurong City, integrated fertilization of strawberries with water and fertilizer was carried out, using the special fertilizer in Example 1 , due to the long planting time of strawberries and the high degree of fertilization of the land, the number of topdressing fertilizers is reduced. During the flowering and fruiting period of each side inflorescence, a total of 7 times of topdressing, every hm 2

[0035] Use 30 kg of fertilizer.

Abstract

The invention discloses a water and fertilizer integration special fertilizer for strawberries in the flowering and seed setting period. The special fertilizer is a water-soluble fertilizer with the total nutrient content of 54%, the nitrogen content of 20%, the phosphorus content of 10% and the potassium content of 24%, and comprises 16.5% of ammonium biphosphate, 26-27.78% of potassium sulfate, 33% of urea, 20.5-22.28% of potassium nitrate, 2% of magnesium calcium nitrate, 0.05% of chelated zinc, 0.05% of cheated boron, 0.08% of chelated molybdenum and 0.04% of chelated manganese. Top dressing is carried out 10-12 times from the flowering, fruit expanding and maturity process to harvesting of the strawberries. The special fertilizer has the advantages of balanced fertilization, no wastes, reduction of wastes of superfluous nutrients, cost saving, environment pollution reduction, immediate use after onsite preparation, and simple use. The special fertilizer can reduce the cost; and the cost of every ton of a commercial water-soluble irrigation fertilizer with same nutrient content with the special fertilizer is about 15000 yuan, and the fertilizer purchasing cost is saved by 65-75%.

Description

technical field [0001] The invention belongs to the field of agricultural technology planting, and in particular relates to a special fertilizer formula for the integration of water and fertilizer in the flowering and fruiting stage of strawberries and a use method. Background technique [0002] Strawberry is known as the "Queen of Fruits", and it is also one of the fruits whose cultivation quality in off-season greenhouses is better than that of conventional open field cultivation. Due to the long fruiting time of strawberry cultivation, it takes nearly 200 days from flowering to fruit picking in the south of the Yangtze River, so it requires a large amount of fertilizer and many times of fertilization. With the increase of the unit price of labor, the cost of labor is also increasing. The combination of strawberry fertilization and drip irrigation forms the integrated technology of water and fertilizer, that is, with the help of drip irrigation system, drip irrigation and ...
