紫外線輻射源對糧食作物的危害可以用尼龍薄膜遮蓋

？因為欠(qian)缺紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)，很多(duo)(duo)(duo)動植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)會(hui)產生(sheng)(sheng)變化。例(li)如蜜峰采不(bu)(bu)上純蜂(feng)蜜，有(you)一(yi)(yi)些(xie)(xie)植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)生(sheng)(sheng)長(chang)發(fa)育(yu)過多(duo)(duo)(duo)，四(si)季(ji)豆和(he)花(hua)的(de)(de)(de)顏色產生(sheng)(sheng)變化。這種(zhong)發(fa)覺限定了(le)(le)能(neng)屏(ping)(ping)蔽(bi)掉紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)的(de)(de)(de)尼龍薄膜的(de)(de)(de)運(yun)(yun)用。但(dan)大(da)家(jia)當然會(hui)想，屏(ping)(ping)蔽(bi)掉紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)對一(yi)(yi)些(xie)(xie)糧食作(zuo)物(wu)(wu)(wu)(wu)(wu)是不(bu)(bu)是有(you)非常好的(de)(de)(de)正臉(lian)功(gong)效？近(jin)(jin)些(xie)(xie)年(nian)的(de)(de)(de)科學研(yan)究確認，屏(ping)(ping)蔽(bi)掉紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)少有(you)三大(da)主要用途:(1)降低病(bing)(bing)(bing)害(hai)。(2)避免花(hua)草樹木脆化，延長(chang)壽命。(3)更改植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)形(xing)狀(zhuang)，提(ti)(ti)升(sheng)多(duo)(duo)(duo)種(zhong)多(duo)(duo)(duo)樣農(nong)(nong)作(zuo)物(wu)(wu)(wu)(wu)(wu)的(de)(de)(de)質量。這類運(yun)(yun)用過去是難(nan)以置信的(de)(de)(de)，由于紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)能(neng)夠(gou)殺掉病(bing)(bing)(bing)菌(jun)(jun)。屏(ping)(ping)蔽(bi)掉紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)會(hui)造(zao)成細(xi)菌(jun)(jun)繁(fan)(fan)殖嗎？實際上，因為植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)在長(chang)期性(xing)的(de)(de)(de)紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)直射下(xia)生(sheng)(sheng)長(chang)發(fa)育(yu)，造(zao)成植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)病(bing)(bing)(bing)害(hai)的(de)(de)(de)細(xi)菌(jun)(jun)、桿狀(zhuang)病(bing)(bing)(bing)菌(jun)(jun)全是具備(bei)一(yi)(yi)定抗(kang)紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)工(gong)作(zuo)能(neng)力的(de)(de)(de)微生(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)種(zhong)，在紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)的(de)(de)(de)功(gong)效下(xia)能(neng)夠(gou)很多(duo)(duo)(duo)繁(fan)(fan)育(yu)，由于紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)殺掉了(le)(le)很多(duo)(duo)(duo)不(bu)(bu)可以抗(kang)紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)但(dan)對植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)沒害(hai)的(de)(de)(de)微生(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)種(zhong)。假(jia)如農(nong)(nong)膜遮蓋紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)，大(da)部分不(bu)(bu)可以抵御紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)但(dan)對活物(wu)(wu)(wu)(wu)(wu)植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)沒害(hai)的(de)(de)(de)微生(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)種(zhong)就會(hui)繁(fan)(fan)育(yu)，進而(er)抑止(zhi)植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)微生(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)的(de)(de)(de)繁(fan)(fan)育(yu)，那樣糧食作(zuo)物(wu)(wu)(wu)(wu)(wu)的(de)(de)(de)病(bing)(bing)(bing)害(hai)就會(hui)大(da)大(da)減少，生(sheng)(sheng)產量就會(hui)提(ti)(ti)升(sheng)。蟲(chong)害(hai)沒有(you)紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)難(nan)以生(sheng)(sheng)長(chang)發(fa)育(yu)繁(fan)(fan)育(yu)，有(you)一(yi)(yi)些(xie)(xie)病(bing)(bing)(bing)毒是由蟲(chong)害(hai)帶上的(de)(de)(de)，因此 這種(zhong)病(bing)(bing)(bing)癥是能(neng)夠(gou)防(fang)止(zhi)的(de)(de)(de)。用農(nong)(nong)膜預(yu)防(fang)病(bing)(bing)(bing)害(hai)不(bu)(bu)貴(gui)，人力成本(ben)也很少。它還能(neng)夠(gou)防(fang)止(zhi)生(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)農(nong)(nong)藥對自(zi)然環境的(de)(de)(de)環境污染(ran)，農(nong)(nong)牧業食品類中沒有(you)農(nong)(nong)殘，因而(er)近(jin)(jin)些(xie)(xie)年(nian)獲得了(le)(le)快速(su)的(de)(de)(de)運(yun)(yun)用。應(ying)用推(tui)廣，可用農(nong)(nong)作(zuo)物(wu)(wu)(wu)(wu)(wu)種(zhong)類愈來愈多(duo)(duo)(duo)。合適預(yu)防(fang)的(de)(de)(de)病(bing)(bing)(bing)害(hai)有(you)稻瘟病(bing)(bing)(bing)、青(qing)枯病(bing)(bing)(bing)、灰霉病(bing)(bing)(bing)、黑斑細(xi)菌(jun)(jun)感染(ran)病(bing)(bing)(bing)害(hai)、爛掉病(bing)(bing)(bing)和(he)軟腐病(bing)(bing)(bing)等(deng)(deng)。蟲(chong)害(hai)包含芽蟲(chong)病(bing)(bing)(bing)害(hai)等(deng)(deng)。除此之外(wai)(wai)(wai)(wai)(wai)，抗(kang)紫(zi)(zi)(zi)外(wai)(wai)(wai)(wai)(wai)線(xian)(xian)(xian)農(nong)(nong)膜能(neng)夠(gou)更改植(zhi)(zhi)物(wu)(wu)(wu)(wu)(wu)形(xing)狀(zhuang)，提(ti)(ti)升(sheng)質量，如提(ti)(ti)升(sheng)果子糖度(du)，改進花(hua)形(xing)狀(zhuang)，避免圓椒(jiao)脆化
