The Brief Introductions for the Fine Hybrid Castor-oil Plant of the Agriculture Science Research Academy of Zibo Shandong China |
Zibima
No.6
1. Yield Performance: the output is 4.58t./ha. by the experiment in
our city in 2003. Compared with “Zibima No.2”, the increased
production is 18.4％. Through the experiments of three place in our city
in 2004, the yields is 4.4 t./ha., 4.784 t./ha., 4.583 t./ha.. Compared
with the contrast, the increased production are10.34％,19.97％,14.93％.
Compared with two years contrast, the average increased production
are15.08％. The output commonly is 4.5 t. /ha. In Xinjiang, the output is
more than 6.75 t./ha.which planted in high produce measures. Single plant
production potential is more than 1,000g.
2.
Characteristics: It takes about 90 days from sowing to the main spikes
ripe. Grow no limit. The plant high is 220 cm, it has 3-4 first branches.
Single plant can grow 7-8 spikes. The spike shape likes a pagoda
.The main spike long 75-90cm. .The capsule has many dense thorns. The seed
shape is an ellipse, and has brown color grain. 100 seeds weight is
about 40g. The kernel rate is 75.4% .The seeds contain oil 50.28%, and the
kernel contain oil 64.46%. 3. The Main Points of Cultivation: It can be planted in the area of the whole country that have no frost time more than 110 days. And it can be grow especially prominent in the area of Northeast, Northwest and North in China. Seedtime: In Middle Region of Shandong Province, the time for spring sowing is from the last ten-day of March to the first ten-day of April. If interline planting of wheat field, the time is in the first ten-day of May. It is suitable to plant in the last twenty days of April for the regions of Northeast and Inner Mongolia of China. Cultivation density: In Middle Region of Shandong Province, row spacing is 100-120 cm; the spacing of two plants is 70-80cm; it can grow 10,500-13,500 plants/ha.. In the regions of Northeast and Inner Mongolia of China, the row spacing is 100-120 cm(it can plant in both side of a ridge ) ; the spacing of two plants is 60cm ; it can grow 13,500-15,000 plants/ha.. In the region that temperature difference is big and sunshine is strong in a day, such as Xinjiang etc., the plants density can be increased to 13,500-18,000 plants/ha. |
