"On May 3, the tissue culture seedlings of 40 mu of rubber trees were cut off smoothly. According to the current situation, compared with the sprout seedlings of the same period, the yield increased by 30%, and the dry content increased by more than two percentage points." Today, in the sea glue group longjiang branch culture seedling demonstration base, the company's production technology department minister he xinghui said happily.
This is the result of cooperation with the rubber institute of the Chinese academy of tropical agricultural sciences (hereinafter referred to as the rubber institute of the Chinese academy of thermal sciences). 2009, ReKeYuan rubber hua-sun huang, director, research team, led by researcher yu-wei hua successful mass produced the "rubber tree from the root young state clone" (commonly known as "the somaclone"), in 2012 the longjiang branch rubber group and the team cooperation, planted the first 7-33-97 somaclone hot research, nowadays, engraftment only six and a half years, I successfully open cut, production well.
Walking into the tissue culture seedling demonstration base of longjiang branch, one after another straight rubber trees are in uniform. These are called "clone trees in the field of rubber", and their potential is amazing.
"Before, the artificial cultivation of rubber trees in China used solid seedlings and bud seedlings." Hua yuwei introduced that these two kinds of seedlings generally need 8 years to open cutting time, low yield, are poor and weak wind resistance. To breed high yield, good resistance to fast-growing, forest consistent degree is high, the rubber tree seedlings, the team to overcome the "to anther or inside bead is as the explant, the primary embryo, embryo proliferation cycle to secondary body plantlet regeneration of the somaclone factory production technology", implements the rubber somaclone mass production application.
Chen hui, a worker who has worked in longjiang branch for 25 years, has witnessed the growth and harvesting of the first rubber tissue culture seedlings. "Tissue culture seedlings are small, averaging more than 20cm in height and require special care, but they grow particularly fast from the second year after transplantation." Recalling more than six years after the transplant, Chen hui said that every time a typhoon came, the rate of tissue culture seedlings falling was low, the trunk was not staggered, and the resistance to wind was good.
Chen hui also said that compared with the traditional 525 line of grafted seedlings, the 7-33-97 line of tissue culture seedlings was transplanted at the same time in the same forest section with it, but the cutting was one year in advance, which could directly feel the advantages of tissue culture seedlings. As for the current output of this year, May 3, 6, 9 and 11 respectively cut the first knife, the second knife, the third knife and the fourth knife, glue output reached 7 kilograms, 10 kilograms, 21 kilograms and 33 kilograms, showing an increasing state. Chen hui takes notebook, introduce the total output of 864 trees that he is in charge of to the 2 trees that he is in charge of to the reporter seriously namely these days.
In fact, since the third year of transplanting rubber tissue culture seedlings, longjiang branch company has clearly realized its advantages and decided to deepen the cooperation with the rubber institute of the Chinese academy of thermal sciences, continuously expand the planting area and actively make use of this technology. At present, the branch rubber tissue culture seedlings planting area has reached 915 mu.
The team developed the somaclone also attracted the attention of the other base glue group branch, since longjiang branch plant, yangjiang branch, dafeng branch, the new branch, wide dam branch and build branch were established in cooperation with ReKeYuan rubber planting rubber somaclone, at present a total of more than 1500 mu planting area.
"Next, the base branches of sealant group should actively cooperate with the rubber institute of the Chinese academy of thermal sciences, expand the planting area of tissue culture seedlings, and transform science and technology into productivity. In the case of low rubber unit price, they should actively seek for ways to increase output." Hai jiao group party secretary, chairman wang renfei said.
