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

A kind of Watermelon Fertilization method

Technical field

The present invention relates to a kind of fruit fertilizer practice field, particularly a kind of Watermelon Fertilization method.

Background technology

Watermelon can be rated as " king in midsummer ", clearly quench one's thirst, taste sugariness succulence, it is good fruit in midsummer, watermelon, except not fatty and cholesterol, contains a large amount of glucose, malic acid, fructose, Argine Monohydrochloride, tomatin and the abundant materials such as vitamin C, is a kind of rich very high nutrition, pure, edible safety food, meat sugar content is generally 5～12%, comprises glucose, fructose and sucrose.

Watermelon is suitable for growing on fertile sandy loam or clay loam, the farmyard manure that happiness is become thoroughly decomposed.According to data, produce 1000kg Watermelon Fruit and need nitrogen (N) 2.5-3.3kg, phosphorus (P2O5) 0.8-1.3kg, potassium (K2O) 2.9-3.7kg.But different growing has obvious difference to the absorptive amount of nutrient, at germination period, account for 0.01%, Seedling Stage accounts for 0.54%, takes out the climing phase to account for 14.6%, fruiting period is the most vigorous period of watermelon absorption nutrient, account for 84.88% of total nutrient amount, watermelon is to need fertile more plant, if but particularly nitrogenous fertilizer is too much for fertilizer, add rainfall or pour water abundant, there will be slightly climingly, the thick climing result that is difficult for, affects the yield of watermelon.Prevent that thick climing way from being that nitrogenous fertilizer is not executed too much, strengthen ventilation and penetrating light, if occur slightly climing before blooming, can extract the climing heart, destroy its growth potential, also can use growth inhibitor to suppress its growth, visible, watermelon later stage nutrition important, common fertilizing method has been ignored the demand of watermelon different phase to Different Nutrients in fertilising process, reduces the yield of watermelon.

Summary of the invention

The object of the invention is to: for the problem of above-mentioned existence, provide a kind of and needed the method for Different Nutrients percentage composition to Watermelon Fertilization according to the different things of watermelon, promote its growth, result, thus when reaching yield production of water melon, guaranteed the nutrient content that it is abundant.

Technical scheme of the present invention is: a kind of Watermelon Fertilization method, and comprise base manure and topdress, in described step base manure, use 500～1000kg for every mu, and sneaked into ash 10～15kg, superphosphate 25～30kg, mixes with soil, earthing, field planting or live, described step is applied fertilizer for the first time in topdressing after the live seedling of watermelon seedlings grows 2 true leaves or the slow seedling of transplanted seedling, apart from seedling 17cm place, opening an arc shallow ridges, every strain seedling execute urea 0.01～0.015kg as help seed manure work as melon seedling take out climing after between strain ditching-fertilizing, every strain 0.05～0.15kg Nitrogen, Phosphorus and Potassium, when water melon young fruit diameter 5cm left and right, ditch again every mu and execute urea 12～16kg, potassium sulfate 5～8kg, during young fruit diameter 10～15cm, execute urea 8～15kg for every mu, potassium sulfate 10～15kg, young fruit expands to fruit maturation, spray 0.5% potassium dihydrogen phosphate, 0.5% nitrate of lime each 2 times.

Most preferredly in described step base manure use 800kg for every mu, and sneaked into ash 13kg, superphosphate 28kg, mixes with soil, earthing, field planting or live.

Adopted its beneficial effect of above-mentioned technical scheme to be: use the growth that appropriate base manure can promote melon seedling, can not postpone breeding time, and take out can be because of nourishing and growing prosperous and affecting result after climing, the suitable base manure of using, the florescence shortens, and pollination time is short.

Watermelon seedlings Root Distribution scope is little, base manure for deep layer is difficult to absorb, mend spraying fertilizer and can promote growth, and take out climing rear growth rate and accelerate, increase in demand to nutrient, this phase topdresses and can promote the melon length of overgrowing, this time fertilising not only can promote but also can solve the needs of melon phase to nutrition, to keeping growing way, the prolongation knot melon phase of plant all favourable, knot melon fertilizer is the key that watermelon topdresses, the absorbing capacity of knot melon phase due to watermelon root system reduces, and can and control worm in conjunction with diseases prevention, with potassium dihydrogen phosphate, carries out top dressing.
