Problems solved by technology

[0003] In the process of tomato cultivation and growth, in order to control the growth of tomato side branches, vegetable growers need to regularly perform operations such as pruning and branching to regulate plant growth. These agricultural operations consume a lot of manpower and time, and the labor intensity is high and the production cost is high.

Embodiment 1

[0015] Example 1 Effect test of smearing strigolactone to inhibit the growth and development of side branches of tomato

[0016] 1. Test materials and test design

[0017] The test material was tomato 'Zhongza No. 9' (the seeds were provided by the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences), and the strigolactone used was a synthetic analog GR24 (purity 99.9%) purchased from Beijing Daqin Xingye Technology Co., Ltd.

[0018] Tomato seedlings were planted in a solar greenhouse and managed according to conventional methods. When the plants grow to 80-90cm, select 30 plants with the same growth potential (divided into 3 groups, 10 plants in each group), and place them at the leaf axils of the main stem branches of the tomato (mark this as the first node position, and order (increase upward) apply strigolactone (GR24) solution, and the treatment is as follows: (1) take the normal growing plants as the control (CK); (2) apply 7.5 μmol·...

Embodiment 2

[0024] Example 2 Injection of strigolactone inhibits the growth and development of side branches of tomato

[0025] 1. Test materials and test design

[0026] The test material was tomato 'Aiji 112' (the seeds were provided by Jiangsu Lvgang Modern Agriculture Development Co., Ltd.), and the strigolactone used was the synthetic analog GR24 (purity 99.9%) purchased from Beijing Daqin Xingye Technology Co., Ltd. .

[0027] Tomato seedlings were planted in a solar greenhouse and managed according to conventional methods. When the plants grow to 80-90cm, select 30 plants with the same growth potential (divided into 3 groups, 10 plants in each group), and place them at the leaf axils of the branch parts of the main stem of the tomato (mark this as the first node position, and sequentially Incremental upward) Injection of strigolactone (GR24) solution, the treatment is as follows: (1) Take normal growing plants as the control (CK); (2) Inject 2.5 μmol·L -1 GR24; (3) Inject 5 μmo...

Embodiment 3

[0033] Example 3 Effect of strigolactone soaking root treatment on inhibiting growth of side branches of tomato

[0034] 1. Test materials and test design

[0035] The test material is tomato 'Shirley' (seeds are provided by Rexwang (China) Seed Co., Ltd.), and the strigolactone used is a synthetic analog GR24 (purity 99.9%) purchased from Beijing Daqin Xingye Technology Co., Ltd. .

[0036] The tomato seedlings are cultivated by the plug seedling method, and the seedlings can be planted and transplanted after they grow 4-5 true leaves. 1-2 days before planting, select 40 seedlings with uniform growth (divided into 4 groups, 10 in each group), wash the roots with clean water, and spray them with a concentration of 10 μmol L -1 , 20 μmol L -1 The strigolactone (GR24) solution was used to soak the root system for 24 hours. Distilled water was used as a control (CK). After 60 days of transplanting, measure the length of the side branches of the first node and above each node...

Abstract

The invention discloses a method for inhibiting the growth and development of side branches of tomato. Exogenously smearing tomato plants with a strigolactone solution with a concentration of 7.5-10.0 μmol L-1; or treating tomato plants with a strigolactone solution with a concentration of 2.5-5.0 μmol L-1 Exogenous injection treatment; or use strigolactone solution with a concentration of 10.0-20.0 μmol·L-1 to soak the root system of tomato seedlings for 20-24 hours 1-2 days before seedling planting. Both exogenous smearing and injection treatment were carried out at the leaf axils of the branches of tomato main stems, and the dosage was 10 μL / plant. The method significantly inhibits the growth and development of tomato side branches, reduces labor consumption and the spread of diseases and insect pests, promotes plant growth and improves yield and quality, has the characteristics of simple operation and no pollution, and is suitable for the cultivation of open-field tomatoes and facility tomatoes.

Description

technical field [0001] The invention relates to a method for regulating the growth and development of plants, in particular to a method for inhibiting the growth and development of side branches of tomato through plant hormones, and belongs to the technical field of vegetable cultivation. Background technique [0002] Tomatoes, also known as tomatoes and foreign persimmons, are native to the tropical highlands of Peru and Ecuador in western America. In recent years, with the rapid expansion of the area of ​​protected vegetables in my country, the area of ​​tomato cultivation has continued to increase, and it has become one of the main vegetable varieties in China, which has played an important role in promoting farmers' income and social and economic growth. Tomato plants have a strong growth potential, and each side bud can germinate to form side branches, blossom and bear fruit. Especially after the plant is topped, more side branches will usually germinate due to the tra...
