茄子抗病又高产嫁接育苗是关键(国外英文资料) Grafted seedlings are the key to the disease resistance and high yield of Eggplant Continuous cropping of eggplant causes Verticillium wilt, Fusarium Wilt and stem base rot to become more and more serious, but the effect of chemical control is not obvious. Grafting and changing roots are the best way to prevent soil borne diseases. Moreover, after grafted eggplant, the plant stress resistance increased, the growth was vigorous, the quality was improved, and the yield was increased. First, choose rootstock, eggplant grafted stock Toru Bam, CRP, Japan Red eggplant, from the production practice, to support Rubam performance best. Toru Bam is highly resistant to Verticillium Wilt and Fusarium wilt, bacterial wilt, nematodes, roots, stems and leaves on the strong growth potential, convenient operation and less thorn, grafting, but small seeds, 1000 grain weight of about 1 grams, the germination is difficult. After the emergence of seedlings, the initial growth was slow, and the growth of the 3~4 leaves accelerated. Two, cultivate the rootstock and soak in water for 7 ~ 8 hours Tuolubamu, make the seeds absorb enough water, then 100 mg / L GA3 for 24 to 48 hours after washing, cast into gauze bags, at germination, day 25 to 30 DEG C, the night of 15 to 20 DEG C, washed 1 times with water daily 7 ~ 8 days, budding. The seeding method of stock is the same as that of eggplant. Because the seedlings are slow, it is necessary to keep the bed soil moist, and the temperature regulation is the same as that of eggplant seedlings. Three, scion seedlings need to sow when the 2 leaves of the stock are sown. When Toru Bam is used as rootstock, the scion should be sown about 25 days later. Four, grafting techniques, when the stock grows to 6~7 leaves, 4~5 cm thick stem, has reached half lignification, you can graft. By then, the grafting method has split and then cutting pick. 1. rely on. The stock and scion and out, with a blade oblique in third to the fourth l
