http://www.hecgloballearning.org.uk/temp/nikeairmax.php Listened Gu Qian, nike free run 2 a confused, nike free to their seed, but the twenty-first century farmers with seeds, then the yield per mu but reached Jiubai of kilograms per mu yield, but here is how only $ 70 kilos? Even converted into twelve pound 30 was 400 jin, only half of the per mu yield of 1.6 pound! Is not where the problem? Feedback from other land and village after another message that the relatively low yield of hybrid rice is not groundless, more than a case, questioning, Gu Qian only hesitated to say the problem of hybrid rice, the promotion of hybrid rice, blighted grain higher rate than ordinary rice production has increased, but is actually just a small part of the production of hybrid rice, most of the hybrid rice production due to the presence of large number of empty unfilled grains, guide led and ordinary rice production almost, in the end, the village of the AU hybrid rice yield per mu will drop down.
What is the reason for food shell? nike free run 3 Do not understand the cultivation of food production are confused, only to the University for help, although the people who the hybrid rice contented so that they have enough to eat, but know this actual production of rice nike free OK chances : yields up nearly Flemingia rice the blighted grain rate is too high makes the actual production is less than half of this is a big problem, not long before the school sent over. Soil trace elements is sufficient, there is no problem of lack of trace elements, the farming method does not it?
nike free Soldier before at home farming, how likely is farming the right way? Why is that? nike free How to forget, the characteristics of the hybrid rice! The production is low because there is no security according to the characteristics of the hybrid rice cultivation! The professor suddenly patted their own brains, came to understand that. Characteristics of hybrid rice? Bunch of people full halo species also have characteristics? Well, the main reason for the hybrid rice blighted grain rate higher is the hybrid rice inherent physiological weaknesses, photosynthetic efficiency is low, the hybrid rice in addition to the tillering stage, panicle initiation, booting and the milky of photosynthetic efficiency are lower than conventional rice, nike free not quite sure why that is, but it is a fact, this is one, and the second is the adaptability of the temperature of the hybrid rice amplitude smaller, easily lead to high or low temperatures hazards, The third is poor resistance to diseases and pests, in the same population density conditions, the plant is exposed insect population is 3 to 4 times that of conventional rice, planting density, fertilization, irrigation for a reason, not lack of soil trace elements, so we should pay attention to pay close attention to the growth of rice, to observe.
