Embodiment 1

[0023] Embodiment 1, output comparison of grafted seedlings of tomato with two sprouts tiller and traditional grafted seedlings after field planting

[0024] Materials: The tomato rootstock variety is Jiulu 787 bred by Beijing Yuzhengtai Breeding Co., Ltd., the scion variety is Zhongza 105 bred by the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences, and the grafting sleeve is provided by Taizhou Longji Plastic Industry Co., Ltd.

[0025] Method: select plump tomato rootstock seeds and scion seeds, soak the seeds in warm soup, and sow them respectively into 72-hole plastic trays filled with peat, vermiculite, and perlite 3:1:1 (v / v) mixed matrix, one for each hole. suitable environment and conventional water and fertilizer management. When the rootstock and scion seedlings reached 3 true leaves, they were grafted with sleeves and grown in the healing room for 8 days, then moved to the glass greenhouse and continued to grow for 6 days. The ...

Abstract

The invention discloses a method for cultivating a grafted tomato seedling with two sprouts. The method mainly includes the steps that a stock species which is resistant to stress and high in water absorption capacity and fertilizer absorption capacity and a scion species which is high in yield and good in quality are selected, the stock and the scion are cultivated to have 2-4 true leaves separately, tube grafting is conducted, after the grafted seedling completely survives, a cutter is used for making a horizontal slash on the embryonal axis portion of the scion of the grafted seedling, the true leaves and an apical growing point are removed, one two cotyledons are maintained, the grafted seedling continues to be cultivated to sprout in the axil, and two side branches are generated. Compared with a traditional grafted tomato seedling, the two side branches which are uniform in growth vigor can be generated, after planting, the two side branches become two fruit bearing main vines, and the good-quality and high-yield cultivation of tomatoes is easily achieved.

Description

technical field [0001] The invention relates to the technical field of vegetable cultivation, in particular to a method for cultivating tomato double-sprouting grafted seedlings. Background technique [0002] Tomatoes are colorful, delicious, and nutritious, and are loved by the majority of residents. They are very important vegetable species in the world and in my country. In recent years, due to continuous cropping and unreasonable fertilization, the problem of tomato cultivation soil barriers has become increasingly prominent, and diseases such as root-knot nematode, bacterial wilt, and canker have become increasingly serious (Huang Yihong, Lei Dongyang. 2013. The effect of grafting tomatoes on different rootstocks against bacterial wilt Research. Jiangxi Agricultural Journal, (1): 73-75; Gao Fangsheng, Wang Lei, Xu Kun. 2014. Comprehensive evaluation of the relationship between rootstock and grafted tomato yield and quality. Chinese Agricultural Sciences, 47(3): 605-612;...
