Abstract

The invention discloses a kind of vegetable cultivation fertilising technique, including following technique：The vegetables time of infertility every 667 square metres of doses are 2000-2500 kilograms of farm manure, and 20 30 kilograms of nitrogenous fertilizer, 5-8 kilograms of phosphate fertilizer, 10-12 kilograms of potash fertilizer additionally includes technique of topdressing, secondary technique and the foliage top dressing technique of topdressing；Technique of wherein topdressing is:35 kilograms of urea, 11-20 kilograms of Diammonium phosphate (DAP), 6-7 kilograms of potassium sulfate, 20 kilograms of calcium nitrate, secondary technique of topdressing is:Every 667 square metres of rosette state applies 10-12 kilograms of urea, 7-9 kilograms of potassium sulfate；Every 667 square metres of balling initial stage applies 10-12 kilograms of urea, 7-9 kilograms of potassium sulfate.The present invention improves quality of vegetable, lifts yield of vegetables.

Description

A kind of vegetable cultivation fertilising technique

Technical field

The present invention relates to growing vegetables technical field, more specifically, more particularly to a kind of vegetable cultivation fertilising technique.

Background technology

Some vegetables water consumption are big, not moisture-proof, and half is cold-resistant, and temperature capacity is poor.Vegetable root system is flourishing, has loose meat straight Root, point root is a lot, forms flourishing netted root system, wherein having 90% to concentrate under earth's surface in 20-30 cm layer of soil.It is required that soil Deeper, the feeder capability sand loam high of layer, suitable soil pH value is 6-6.8.Vegetables are unable to continuous cropping, also can not be with it Its brassicaceous vegetable crop rotation.Vegetables are general in early August sowing, and early November harvests, with the improvement of cultivation technique, at present The vegetables of winter facility cultivation are also fairly common in some places.The growth cycle of vegetables includes nutrient growth and reproductive growth two Individual period, nutrient growth is divided into germination period, Seedling Stage, rosette state, heading stage, rest period, and reproductive growth is divided into peduncle-growing period for rapeseed, blooms Phase and fruiting period.Vegetables breeding time is long, and yield is high, and nutrient demand amount is very big, and the uptake to potassium is most, next to that nitrogen, calcium, Phosphorus, magnesium.Often producing 1000 kilograms of vegetables about needs 2.2 kilograms of absorbed nitrogen, 0.94 kilogram of phosphorus, 2.5 kilograms of potassium.Because vegetables are different The increment of growthdevelopmental stage is different with the speed of growth, and the demand to nutritional condition is also differed.Total nutritive peculiarity is:Seedling stage inhales Adopt point less, nitrogen, phosphorus, the 10% of the uptake deficiency gross absorption of potassium；Rosette state showed increased, account for total amount 30% is left It is right；Heading stage absorbs nutrient at most, accounts for 60% of total amount or so.Sufficient nitrogen nutrition is to promoting to form loose leaf-head and carry High photosynthesis efficiency has especially important meaning, if nitrogenous fertilizer is excessive, leaf is big and thin, and core is unreal, and poor quality is not shelf-stable； If Nitrogen supplying is not enough, plant can be made short and small, organize thick and stiff, Severe Reduction.

The content of the invention

It is an object of the invention to provide a kind of vegetable cultivation fertilising technique.

In order to achieve the above object, the technical solution adopted by the present invention is as follows：

A kind of vegetable cultivation fertilising technique, including following technique：The vegetables time of infertility every 667 square metres of doses are farmers' 2000-2500 kilograms of fertilizer, 20-30 kilograms of nitrogenous fertilizer, 5-8 kilograms of phosphate fertilizer, 10-12 kilograms of potash fertilizer additionally includes work of topdressing Skill, secondary technique and the foliage top dressing technique of topdressing；

Technique of wherein topdressing is:3-5 kilograms of urea, 11-20 kilograms of Diammonium phosphate (DAP), 6-7 kilograms of potassium sulfate, calcium nitrate 20 Kilogram,

Secondary technique of topdressing is:Every 667 square metres of rosette state applies 10-12 kilograms of urea, 7-9 kilograms of potassium sulfate；Balling Every 667 square metres of initial stage applies 10-12 kilograms of urea, 7-9 kilograms of potassium sulfate；

Foliage top dressing technique is:1. calcium chloride or calcium nitrate are sprayed, 5-8 days before vegetables harvest, spray 0.4%- 0.7% calcium chloride solution or 0.25% -0.5% calcium nitrate solution；2. urea is sprayed, 0.5% is sprayed at the balling initial stage- 1.0% urea liquid；3. potassium dihydrogen phosphate is sprayed, the rosette state to heading stage can spray 0.2% potassium dihydrogen phosphate, every 7- Spray once within 10 days, spray altogether 3 times；4. sprayed boric fertilizer, with 0.15% borax soln or 0.1% BAS, exists respectively Vegetables rosette state and the foliage spray of core phase, every 667 square metres with 75-double centner of solution.

Preferably, by the farm manure 2000-2500 kilograms replace with 300-350 kilograms of Commodity Organic Fertilizer.

Compared with prior art, the advantage of the invention is that：Vegetable Fertilizing technique comprehensive nutrition of the invention, improves soil Environment, improves quality of vegetable.

Specific embodiment

The preferred embodiments of the present invention are described in detail with reference to embodiment, so that advantages and features of the invention Can be easier to be readily appreciated by one skilled in the art, apparent clearly be defined so as to be made to protection scope of the present invention.

A kind of vegetable cultivation fertilising technique, a kind of vegetable cultivation fertilising technique, including following technique：The vegetables time of infertility is every 667 square metres of doses are 2000-2500 kilograms of farm manure, 20-30 kilograms of nitrogenous fertilizer, 5-8 kilograms of phosphate fertilizer, potash fertilizer 10-12 thousand Gram, additionally include technique of topdressing, secondary technique and the foliage top dressing technique of topdressing；

Foliage top dressing technique is:1. calcium chloride or calcium nitrate are sprayed, heartburn is a kind of common physiology venereal disease in vegetables production Evil, 5-8 days before vegetables harvest, calcium chloride solution or 0.25%-0.5% calcium nitrate for spraying 0.4%-0.7% are molten Liquid；2. urea is sprayed, urea is sprayed, the commodity rate of vegetables can be improved, improve commodity value, 0.5% -1.0% is sprayed at the balling initial stage Urea liquid；3. potassium dihydrogen phosphate is sprayed, the rosette state to heading stage can spray 0.2% potassium dihydrogen phosphate, was sprayed every 7-10 days Apply once, spray altogether 3 times；In the morning, dusk or cloudy whole day can all be sprayed；4. sprayed boric fertilizer, with 0.15% borax soln Or 0.1% BAS, respectively in vegetables rosette state and the foliage spray of core phase, every 667 square metres with solution 75-100 thousand Gram, there is preferable production-increasing function.

Vegetable Fertilizing technique comprehensive nutrition of the invention, improves quality of vegetable, lifts yield of vegetables.
