Problems solved by technology

However, the balanced production of seedlings cannot be achieved by using this technology, which shows that there are fewer early stages and more late stages, that is, only one seedling can be cultivated in the first batch, and 2 to 3 seedlings can be cultivated in each subsequent batch using the lateral buds germinated fr

Embodiment 1

[0026] This embodiment provides a seed multi-batch circulation balanced production method for cultivating multiple tomato grafted seedlings, including the following steps:

[0027] S1: Simultaneous precision sowing of scion and rootstock

[0028] Tomato scion and grafted rootstock seeds are sown at the same time. The grafted rootstock and scion seeding rate ratio of this embodiment is about 3.5:1. Spray 2 times, spray once every 7d, prevent the seedlings from growing too much, and promote the dark green and thick leaves; the grafted stock variety in the present embodiment is the No. 1 variety of sea egg root stock, and this kind is faster than the Torubalu stock growth rate;

[0029] S2: Excision of scion terminal buds

[0030] When the tomato scion in the step S1 grows to 3-4 leaves and 1 heart, cut off the top bud of the main stem of the scion at 45° at the first true leaf and the second true leaf, to obtain the tomato scion seedlings with the top bud and the top bud remove...

Embodiment 2

[0043] In this example, Haiqizhen No. 1 bred by the Vegetable Research Institute of Hainan Academy of Agricultural Sciences was used as the rootstock, and the tomato variety Qianxi bred by Taiwan Nongyou Seedling Co., Ltd. was used as the scion, 60-75 days before the first batch of production orders , No. 1 and Qianxi were sown at the same time; 30 to 35 days after sowing, when Qianxi grew to 3 to 4 leaves, cut off the top bud at 45° at the first true leaf of Qianxi, and cut off the top with The millennium seedlings of the buds are used to cultivate side buds; the cuttings of the millennium are cultivated in the seedling medium with the terminal bud cuttings. After 15 to 20 days, the millennium cuttings quickly took root and 2 to 3 new true leaves were born, and the 2 to 3 side buds germinated from the main stem of the millennium seedlings without terminal buds grew to 2 to 3 true leaves. No. 1 has grown to 5-6 leaves and one heart, and this is the most suitable period for tom...

Abstract

The invention relates to the technical field of tomato grafting, and discloses a cultivation method for cyclic balanced production of multiple tomato grafted seedlings from one seed in multiple batches. The cultivation method comprises the steps of precision seeding of scions in advance, cutting of terminal buds, cuttage of the terminal buds to form seedlings, germination promotion of lateral buds and sleeve grafting. Through multi-batch cyclic balanced production of one seed, 3-4 tomato grafted seedlings can be produced at the same time in each batch. According to the method, the scion variety and the stock seed number can be effectively reduced, and the seed and production management cost is greatly reduced; and moreover, the construction method effectively solves the problems that the existing lateral bud grafting seedling raising technology has few seedlings in the early stage and more seedlings in the later stage, the supply is unbalanced, the management cost of stock staging sowing is high and the like.

Description

technical field [0001] The invention relates to the technical field of tomato grafting, in particular to a method for cultivating multiple tomato grafted seedlings produced in multi-batch cycle and balanced production from one seed. Background technique [0002] Tomato fruit is rich in nutrients and unique in flavor. It is rich in carotene, lycopene and other nutrients. It is a strong antioxidant that can effectively remove free radicals in the body, prevent and repair cell damage, and inhibit the proliferation and replication of cancer cells. , so it is favored by consumers and has been widely planted around the world as an important edible fruit and vegetable. The planting, processing and export of tomatoes in my country are in a continuous growth trend. After more than 20 years of development, my country has become an important producer and exporter of high-quality tomato products in the world, and it is the country with the largest tomato planting area and the highest out...
