But Rice also has a great flaw,fake ray ban sunglasses, water demand, high production costs. And it is the annual crop, usually harvested once, you must re- seeding, or even in the same year, renewable harvest, yields always greatly decreased, and high-yielding hybrid rice seed is not, so the farmers on seed costs is not low. Also suitable for cultivation of many of the main producing areas in southern foothills, farmland transformation costs are too high, the mechanization of production is difficult to engage them, only to completely rely on manpower, but in rural areas where per capita land area per farmer too little now, where to retain labor, so the system will be abandoned or changed culture phenomenon not uncommon single-season seasons change, the national grain output declining.

Both multiples are 12 chromosomes of plants,cheap ray bans, is likely to remain in the chromosomes in the two polyploid plants. Species such newly generated both double cropping of rice can be cooked or even three characteristics, but also the ability to fast-growing bamboo, as well as the ability perennial, without the need to be planted on a quarterly basis, but does not require frequent irrigation, saving a lot of water resources. Unfortunately, that time due to limited funding, and there is no suitable material for experiments, after several experiments failed, this attempt is terminated.

First Army had taken back the fairy millet material for tissue culture,ray ban, first get a lot of material to say, even when not fused successfully, under ordinary conditions cents millet is a perennial plant, as long as they shorten their maturity is also a good variety, even in quality stronger than rice do not know how many times. Tissue culture technology looks very simple, but the operator does not require a low, under the same conditions, some people can be successful once, while others may also fail scores a hundred times, this is the ability to operate on difference.
