Description
Technical field
The present invention relates to fertilizer technology, particularly a kind of pineapple special-purpose foliage fertilizer technology.
Background technology
Pineapple (Ananas comosus (L.) Merr) originates in tropical America, is the big tropical fruit in third place in the world, also is the seventh-largest fruit in the world.China's pineapple cultivation approximately originates from mid-term in 16th century, China has become the world the fourth-largest pineapple producing country now, in production of world pineapple and trade, occupy critical role, pineapple industry is also just becoming the geographic important industry of China's torrid zone south subtropics, plays an important role for increasing local farmers' income.
China's pineapple essential species is implanted in the Lezhou Peninsula, Guangdong, Wanning, Hainan, Qionghai, Chang River, the southeast, Guangxi, Xishuangbanna, Yunnan, Dehong, hilly uplands (gradient is at 0 °-35 °) such as Longhai City, Fujian, Zhangpu.China's pinery soil texture has sand, sandy loam, loam, clay loam, clay.In China Lezhou Peninsula and Guangxi, Yunnan pineapple plantation area partly, its fertilization mode adopts trench digging fertilising (comprise base manure and topdress) mostly and fertilization mode combines to spread fertilizer over the fields (foliage-spray is also adopted in part area, the Lezhou Peninsula), and Hainan, Fujian sand, sandy loam pinery are adopted mostly and are spreaded manuer in holes and spread fertilizer over the fields the fertilization mode that combines.In recent years, in order to improve output, China pineapple plantation area, particularly higher planting density (per hectare plantation 5.4-7.5 ten thousand strains) has been adopted in China pineapple main producing region-Lezhou Peninsula, having strengthened foliage fertilizer on fertilizing method uses, because foliage fertilizer can provide certain moisture and nutrient, satisfied the pineapple process of growth to a certain extent to moisture and nutrient requirement, thereby pineapple output is further improved.
At present, the pineapple leaves leaven of orchard worker's autogamy nearly all is to be mixed by urea, calcium superphosphate, Repone K, binary or Nitrogen, Phosphorus and Potassium.Because it is too high that the calcium superphosphate in the foliage fertilizer contains free acid, the pineapple leaf of burning easily, thus influence its growth; And the nitrogen accounting example in these foliage fertilizers is too high, and potassium accounting example is low excessively, causes the prosperous length of pineapple, and blade is long, and blade is narrow, and stem is little, finally causes single fruit weight low, thereby has reduced pineapple output.In addition, trace element during pinery soil lacks easily, as magnesium, iron, zinc, boron etc., particularly solubility shortage ferrous, replacement property magnesium can cause pineapple plant iron deficiency, magnesium deficiency in the soil, iron, magnesium deficiency have reduced the pineapple leaf chlorophyll content, thereby reduce pineapple photosynthate turnout, influence pineapple growth and pineapple output.But contain iron, zinc, boron nutrition element in the foliage fertilizer of orchard worker's autogamy hardly, the magnesium nutrition constituent content is also less, can not satisfy the pineapple needs that grow.
Therefore, grow and nutrient demand rule and China's pinery soil supplying nutrient capability according to pineapple, a kind of pineapple special-purpose foliage fertilizer and application process thereof of suitable China are provided, this is for improving China's pineapple yield and quality, improve utilization rate of fertilizer, reduce environmental pollution, will have great importance.

The application process of a kind of pineapple special-purpose foliage fertilizer of the present invention is: foliage fertilizer is dissolved in the water by 10%-18% concentration, then from kind after began to carry out foliage-spray in 20-30 days with shower nozzle, stopped in preceding 1 month until flower forcing, sprayed 1-2 time in every month, spray 10-15 time altogether, each per hectare sprays 800-1000 and rises solution; Or above-mentioned foliage fertilizer is dissolved in the water by 0.05%-0.12% concentration, then from kind after began to carry out foliage-spray in 20-30 days with little band sprinkling irrigation mode, stopped in preceding 1 month until flower forcing, sprayed 1-2 time in every month, spray 10-15 time each per hectare 80-100 cubic meter solution altogether.
Key problem in technology point of the present invention is:
1, the present invention fully takes into account the pineapple plant needs and soil supplying nutrient capability nitrogen, phosphorus, potassium.Though the pineapple plant needs the potassium amount more than nitrogen, in the pineapple growth prometaphase, pineapple obtains nitrogen than the plain much less of potassium from soil.Because in the pineapple growth prometaphase, the stubble residual organic matter had consumed a large amount of nitrogens in the soil before the pinery soil microorganisms was decomposed, and consumed less to phosphorus, potassium.Through leaf surface spraying test, with N: P
2O
5: K
2O=1: 0.25: 0.70 ratio meets pineapple grows to nitrogen, phosphorus, potassium nutrition needs, if nitrogen is too high, and the prosperous length of pineapple, leaf is thin, and leaf is narrow, and stem is little, is unfavorable for the accumulation of leaf photosynthesis and carbohydrate, finally reduces pineapple increment and output; If potassium is too high, then the pineapple leaves look lighter, and chlorophyll content is few, is unfavorable for that also pineapple leaf carries out photosynthesis, thereby reduce pineapple output.
Though 2 soils in south china contain a large amount of iron, mainly the form with ferriferous oxide exists, and can not be utilized by plant absorbing.Under acid and reductive condition, the solubleness of iron cpd increases, and can just significantly be increased by replacement attitude iron, the water-soluble iron that plant absorbing is utilized.But pineapple is the living crop of drought, its planting-site mostly is the hilly upland of arid greatly, redox potential is higher around the root system, its root system surrounding soil lacks replacement attitude iron, water-soluble iron, the special replacement attitude, water-soluble ferrous that lacks, because the pineapple root system can only absorb replacement attitude, water-soluble ferrous, so very easily lack the iron nutritive element in the pineapple growth and development process.Iron is difficult for moving in the plant body in addition, and soil application is ferrous very easily to lose efficacy to oxidation again, just becomes an effective means that promotes that pineapple grows so often carry out ferrous supply from the blade face.
3, pineapple is planted mostly in hilly upland, comparatively lacks magnesium, zinc, boron nutrition element, and pineapple is bigger to the magnesium requirement, thereby replenishes trace element in these, plays an important role for promoting pineapple to grow.
4, adopted urea in the pineapple special-purpose foliage fertilizer of the present invention, be because urea is small-molecule substance, easily by the pineapple Foliage Absorption, be difficult for causing that the blade face burns, and the energy decomposing urea utilized nitrogen wherein after pineapple absorbed, and the carbonic acid gas that discharges after decomposing can carry out photosynthesis for the pineapple absorption again, if nitrogen all adopts ammonium ion in the foliage fertilizer, the pineapple leaf of then very easily burning; The magnesium sulfate heptahydrate price is more cheap than water or anhydrous magnesium sulfate, and the Zinc Sulphate Heptahydrate price is more cheap than water or anhydrous magnesium sulfate, and the borax price is more cheap than boracic commodity preparation.
Adopt pineapple special-purpose foliage fertilizer of the present invention after plantation, to spray in 20-30 days, sprayed 1-2 time in every month, spray 10-15 time altogether, can obviously improve pineapple leaves chlorophyll content, pineapple leaves length, width and increase the pineapple leaf number with the form of foliage applying.Pineapple output, fruit commodity rate and the soluble solid content that the pineapple special-purpose foliage fertilizer is handled compared respectively according to increasing by 16.0%, 11.8%, 7.9%.Pineapple special-purpose foliage fertilizer of the present invention possesses following advantage:
1, nutrient content is complete, has solved micro-problem in the pineapple potentiality shortage, has promoted that obviously pineapple grows, and improves the pineapple yield and quality.
2, nutrient reasonable ratio meets pineapple nutrient demand and fertilizer provision from soil characteristics, has solved pineapple nutrient imbalance problem, promotes that pineapple grows, and can improve utilization rate of fertilizer, reduces environmental pollution.
3, safe, be difficult for producing fertilizer damage.
