However, there are obvious differences in the amount of nutrients absorbed by different growth stages. It accounts for 0.01% in the germination stage, 0.54% in the seedling stage, and 14.6% in the vine stage. 84.88%, watermelon is a plant that needs a lot of fertilizer, but if there is too much fertilizer, especially nitrogen fertilizer, coupled with rainfall or sufficient irrigation, thick vines will appear, which are not easy to bear fruit and affect the yield of watermelon

Embodiment 1

[0010] In the watermelon garden, apply 500kg of base fertilizer per acre, and mix in 15kg of plant ash and 30kg of superphosphate, mix with soil evenly, cover with soil, plant or live broadcast. When the live seedlings of watermelon seedlings grow 2 true leaves or after the transplanted seedlings are slowly seedlings, carry out the first topdressing and fertilization, open an arc-shaped shallow ditch at a distance of 17 cm from the seedlings, and apply 0.01 kg of urea to each seedling as a seedling fertilizer. After the melon seedlings are taken out, fertilize by ditching between the plants, 0.05kg of ternary compound fertilizer per plant, and when the diameter of the young watermelon fruit is about 5cm, then ditch and apply 12kg of urea and 8kg of potassium sulfate per mu, and when the diameter of the young watermelon is 15cm, Apply 8 kg of urea and 15 kg of potassium sulfate per mu. Spray 0.5% potassium dihydrogen phosphate and 0.5% calcium nitrate twice each before the young...

Embodiment 2

[0012] Apply 800kg of basal fertilizer per acre in the watermelon garden, and mix in 13kg of plant ash and 28kg of superphosphate, mix with soil evenly, cover with soil, plant or live broadcast. When the live seedlings of watermelon seedlings grow 2 true leaves or after the transplanted seedlings are slowly seedlings, carry out the first topdressing and fertilization, open an arc-shaped shallow ditch at a distance of 17 cm from the seedlings, and apply 0.015 kg of urea to each seedling as a seedling fertilizer. After the melon seedlings are taken out, fertilize by ditching between the plants, and use 0.10 kg of ternary compound fertilizer per plant. When the diameter of the young watermelon fruit is about 5 cm, then ditch and apply 16 kg of urea and 5 kg of potassium sulfate per mu. When the diameter of the young fruit is 10 cm, Apply 15kg of urea and 10kg of potassium sulfate per mu. Spray 0.5% potassium dihydrogen phosphate and 0.5% calcium nitrate twice each before the young...

Embodiment 3

[0014] Apply 700kg per acre of base fertilizer in the watermelon garden, and mix in 12kg of plant ash and 25kg of superphosphate, mix with soil evenly, cover with soil, plant or live broadcast. When the live seedlings of watermelon seedlings grow 2 true leaves or the transplanted seedlings are slowly fertilized for the first time, an arc-shaped shallow ditch is opened at a distance of 17 cm from the seedlings, and 0.02 kg of urea is applied to each seedling as seedling fertilizer. After the melon seedlings are pulled out, ditches and fertilizes between the plants, with 0.10 kg of ternary compound fertilizer per plant. When the diameter of the young watermelon fruit is about 5 cm, then ditches and fertilizes 12-16 kg of urea and 5-8 kg of potassium sulfate per mu. When the height is 12 cm, apply 3 kg of urea and 11 kg of potassium sulfate per mu. Spray 0.5% potassium dihydrogen phosphate and 0.5% calcium nitrate twice each before the young fruit expands until the fruit matures. ...

Abstract

The invention discloses a watermelon fertilizing method, and belongs to the technical field of fruit fertilizing. The method comprises the following steps: 1, base fertilizer application: applying farmyard manure to soil, adding plant ash and calcium superphosphate, uniformly mixing with soil, covering soil, and planting or directly sowing ; and 2, additional fertilization: carrying out first time fertilizer application after directly sowed sprouts of watermelon seedlings have two true leaves or transplanted sprouts recover, applying urea to the sprouts as a seedling assisting fertilizer when the watermelon sprouts vine, applying a ternary composite fertilizer between the sprouts after the sprouts vine, carrying out trenching urea and potassium sulfate fertilizer application during the appearance of young fruits of the watermelons, and respectively spraying 0.5% potassium dihydrogen phosphate and 0.5% calcium nitrate two times before maturation. Fertilization is carried out according to the difference of nutrients required by the watermelons in different stages, and sufficient nutrients are provided for the watermelon sprouts in each stage in order to make the watermelon sprouts rapidly grow, so high yield and economic benefit improvement are realized.

Description

technical field [0001] The invention relates to the technical field of fruit fertilization, in particular to a watermelon fertilization method. Background technique [0002] Watermelon is called "the king of midsummer". It is refreshing and thirst-quenching, sweet and juicy. It is the best fruit in midsummer. Apart from fat and cholesterol, watermelon contains a lot of glucose, malic acid, fructose, protein amino acid, tomato element and rich vitamin C, etc. Substance is a kind of food rich in high nutrition, pure and safe to eat. The sugar content of meat is generally 5-12%, including glucose, fructose and sucrose. [0003] Watermelon is suitable for growing on fertile sandy loam or clay loam, and likes well-rotted farmyard manure. According to data, the production of 1000kg watermelon fruit requires 2.5-3.3kg of nitrogen (N), 0.8-1.3kg of phosphorus (P2O5), and 2.9-3.7kg of potassium (K2O). However, there are obvious differences in the amount of nutrients absorbed by dif...
