1.Variety characters of Lindao No.10Based on a series of experiments and studies, the characters in growth duration of'Lindao 10'were found out.'Lindao 10'is of a little later maturity with about 155 days of growth duration from seeding to heading and has height averaging 95-105cm tall in culm length with good canopy architecture . It has erect pubescent leaf blades , tough culm ,deep green leaf , strong photosynthesis, quick speed of dry matter accumulation and good mature color of grains . And it turns green quickly after transplanted in the field , tillers early, fruits at a high rate, grows roots flourishingly and doesn't age early in the last stage . It is high resistant to rice blast and bacterial blight of rice, but medium susceptible to sheath and culm blight of rice .It has a wide adaptability, high lodging resistance and good tolerance of fertilizer. Its ear is like a club and the ear is big with about 100-130 grains closed tightly and weigh 26-27g per thousand seeds .The number of effective ears is 190-220 thousand per ha. and its yield performance is over 9750kg/ha.2. Technology of raising older , strong seedling under drought conditionThe result showed the technology based on'less seeding-rate ,promoting at first, controlling at last'is much better than the traditional planting way , which raising older long seedlings in the way of'control first , promote later'. The changed quantity of seeds is 300-375kg / ha instead of the traditional quantity of 525-600kg / ha. This change didn't affect the total group, but enhanced individual plant growth and development .When sowing ,cover a shallow layer of soil on the seeds then cover plastic membrane on soil so as to promote early tillering . During the growth of seedling , take care of irrigations and fertilizations in the former stage . Usually, water and fertilize the seedling when two and half leaves appear so that promote tillering at low-place early . After the seedling entering the later growth, control the use of water and fertilizer in order to make the organization strong, especially , let the seedlings keep a little thirsty of water for 5-7 days before transplanting. This management can make the seedling continue to grow directly without stopping after transplanted into the field and produce new roots and branches quickly .3. High yield cultivationBased on the analysis on the factors consisted of rice yield, the key factors which...
