Soil is all crop are born raise this, without soil, do not talk to go up all agricultural production. And chemical fertilizer, also had very main effect in the course that agriculture produces, chemical fertilizer is increase production increases the requirement that close, want land is not fed by chemical fertilizer thin, be about reasonable use good chemical fertilizer. We tell later development how to feed soil " fat " , how to feed crop " fat " .
What is the character with a the most precious fertile soil. Breathe freely the fertility that show water is good, beneficial microbial active is tall, spoken parts in an opera is a good environment, give crop root system a good breath, environment that absorbs nutrition. Describe a nice young person before, how say come, root Gong Miaozheng, that is one's previous experience good ah. Pull far, anyhow a word, edaphic fertility is very important, it is good to want fertility, want beneficial microbial active tall, it is good to should protect water to protect fertilizer to protect permeability, next we all transforming the job is done around this center.
The first, base manure takes the organic fertilizer with use complete, high grade become thoroughly decomposed seriously. Become thoroughly decomposed is not complete, the harm is quite great, burn seedling, earth to pass the problem such as disease to happen from time to tome, as to high grade and organic fertilizer be normal manufacturer amounts to mark through examining content, the mainest is the organic fertilizer with heavy metal not high content. I am very babyish perhaps, what look to heavy metal content is very heavy. Heavy metal is eroding a harm to wear now feed our land, content of edaphic heavy metal exceeds bid, through accumulate over a long period, content of crop heavy metal also can exceed bid, what endanger finally still is our individual health, hear content of heavy metal of some brand paddy to exceed bid how many times, content of some heavy metal exceeds some food mark, if things go on like this, our fitness, unimaginable.
The 2nd, use high grade microbial bacterium fat product. High grade and effective microbial bacterium fertilizer can promote soil beneficial microbial bacterium group breed and development, through beneficial microbial action can increase soil in organic qualitative content, can make soil resume granule construction, improve soil breathe freely the physical performance that shows water to protect water to protect fertilizer. Use microbial bacterium fertilizer to want to notice the choose and buy is normal of course manufacturer qualification product, use method wants reasonable, cooperate organic fertilizer to be used together for instance, escape chemical fertilizer is used etc.
The 3rd, when fertilizing at ordinary times, notice employ is high grade organic fertilizer, contain algal acerbity Shui Rong for instance fertilizer is algal fertilizer, high grade contain humic fertilizer of acerbity Shui Rong. Will complement what soil lacks is organic qualitative, 2 come organic grow to crop character the effect that has cannot be replaced, resemble person life pressure is great now, have a medical check-up the examination does not give unusual state, but often exhaustion waits inferior healthy state, high grade organic the recuperation action with qualitative very good to one arriving since crop meeting. For instance high grade humic acid can raise floral to fight go against ability and raise yield, spur the growth of a ministry, absorb character to nurture directly especially, still can quicken segmentation, stimulate floral to grow thereby.
The 4th, reasonable and right amount use fertilizer, grow according to crop demand characteristic uses right amount and inorganic fat top application. At present nitrogenous fertilizer is use excessive commonly, want control to use. Take potash fertilizer seriously but do not want excessive to use. Use phosphate fertilizer of right amount and high grade water-solubility. Do not use as far as possible a few have filler, the fertilizer with much remain, these were accumulated is the salinity in big canopy, slowly, soil is worse and worse, granule structure of soil was destroyed, airtight, waterproof, root system breathes not free, how will absorb nutrient, still let do not let healthy and strong of seedling of small young plant grow? The level that at present fertilizer of dissolve of many element water reached to develop quickly, big in microelement is all ready, use rising is convenient and quick more, but are you built, fertilizer of dissolve of many element water and fertilizer of dissolve of many element water but different, for instance, the origin of potassium, potassium chloride or potassium sulfate or potassium nitrate, phosphoric acid 2 hydrogen Potassium, it is agricultural class or industrial level, heavy metal content achieves a requirement, the PH value of the product, EC is worth how, can you accomplish craft stability constant? Water dissolve fat doorsill is low now it is truth, but had made the product, do fine, do stable, achieve highest effect, use result best, still be it is so easy to do not have, close people want sharpen one's eyes well choose and buy. Anyhow a word, right amount and timely uses what do not have remain high gradely many element fertilizer. General seedling stage is used balanced model growth of recipe stimulative plant, tall phosphor recipe is used to cooperate compensatory boron, zinc to wait before blossomming can promote bud become divided, fruit and autumn use tall Potassium recipe to promote gains growth and maturity.
The 4th, the microelement in complement. The microelement in although say to also be met inside fertilizer of dissolve of water of many now element,be being added, but, after all crop is right in of microelement sensitive reach demand level different, manufacturer can be added only little in microelement. According to different crop, different canopy earth, fertility of different plot soil is different, watermelon is for instance big to calcic demand, for instance tomato because use potassium excessive be short of magnesium easily, for instance the crop of southern mostly acidity soil appears easily the symptom that is short of iron and phenomenon, the foliaceous leavening dough that contains zinc, boron is used to cooperate phosphate fertilizer to be able to be promoted before blossomming for instance again blossom. More reasonable than wanting as soon as possible like fructification use calcium is fat, for instance filling magnesium can defer crop consenescence to raise photosynthesis. Anyhow everybody can choose according to particular case right amount in microelement replenishers, shi Weijia of gush of general face of blade, had absorbed, utilization rate is high.
