Problems solved by technology

[0003] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: the traditional tomato seedling cultivation technology tends to cause the seedlings to grow excessively due to factors such as the plug seedling cultivation environment, resulting in a decline in the quality of the seedlings
For this reason, in production, the method of spraying growth inhibitors is often used to control the excessive growth of seedlings, but the types and quantities of growth inhibitors currently used are relatively chaotic, which often leads to hormone poisoning of seedlings
At the same time, conventional growth inhibitors have residual toxicity hazards to the following crops

Embodiment 1

[0016] Example 1. Tomatoes were cultivated in a solar greenhouse with delayed stubble in autumn. The planting variety was Dilio. It was sown on July 1 and planted on August 5. The place was in a vegetable greenhouse in Shouguang, Shandong.

[0017] Process 1: Adopt the method of the present invention to raise seedlings:

[0018] For seedling cultivation in plug trays, mix peat, vermiculite and perlite evenly in a volume ratio of 6:3:1, put them into seedling trays, sow seeds, and then put the seedling trays into the seedbed to raise seedlings. When the two true leaves of the tomato seedlings are fully unfolded, place the seedling tray in the functional liquid, take out the seedling tray after the peat is completely soaked, put the seedling tray back into the seedbed to continue seedling cultivation; the functional liquid is composed of the following components : Choline chloride 0.03%, prohexadione calcium 0.003%, boric acid 0.5%, the balance is water.

Embodiment 2

[0025] Example 2, Tomatoes were cultivated in the solar greenhouse in early spring. The planting variety was Baoli. It was sown on December 10 and planted on January 25 of the second year. The location was in a vegetable greenhouse in Shouguang, Shandong.

[0026] Process 1: Adopt the method of the present invention to raise seedlings:

[0027] For seedling cultivation in plug trays, mix peat, vermiculite and perlite evenly in a volume ratio of 6:3:1, put them into seedling trays, sow seeds, and then put the seedling trays into the seedbed to raise seedlings. When the two true leaves of the tomato seedlings are fully unfolded, place the seedling tray in the functional liquid, take out the seedling tray after the peat is completely soaked, put the seedling tray back into the seedbed to continue seedling cultivation; the functional liquid is composed of the following components : Choline chloride 0.015%, prohexadione calcium 0.004%, boric acid 0.8%, the balance is water.

Embodiment 3

[0034] Example 3, Tomatoes are cultivated in the solar greenhouse in winter and spring. The planting variety is Provence. It was sown on September 5 and planted on October 10. The location is in a vegetable greenhouse in Shouguang, Shandong.

[0035] Process 1: Adopt the method of the present invention to raise seedlings:

[0036] For seedling cultivation in plug trays, mix peat, vermiculite and perlite evenly in a volume ratio of 6:3:1, put them into seedling trays, sow seeds, and then put the seedling trays into the seedbed to raise seedlings. When the two true leaves of the tomato seedlings are fully unfolded, place the seedling tray in the functional liquid, take out the seedling tray after the peat is completely soaked, put the seedling tray back into the seedbed to continue seedling cultivation; the functional liquid is composed of the following components : Choline chloride 0.02%, prohexadione calcium 0.0035%, boric acid 0.7%, the balance is water.

Abstract

The invention provides a method mixing choline chloride and prohexadione calcium to cultivate tomato strong seedlings. The method comprises the steps of evenly mixing grass carbon, vermiculite and perlite according to the volume ratio of 6:3:1 to be put into a seedling culturing tray, sowing seeds, then placing the seedling culturing tray into a seed bed to culture seedlings, placing the seedling culturing tray into functional liquid when two main leaves of the tomato seedlings completely spread, taking out the seedling culturing tray when the grass carbon is completely soaked, and placing the seedling culturing tray into the seed bed again to culture the seedlings. The functional liquid comprises 0.015%-0.03% of choline chloride, 0.03%-0.04% of prohexadione calcium and 0.5%-0.8% of boric acid, and the rest is water. In a seedling culturing process, not any plant growth regulating agent is sprayed and fertilized, the excessive growth of the tomato seedlings is controlled, and side effects caused by spraying and fertilizing general growth inhibitors are effectively avoided. In addition, cultured seedlings are better than existing general seedlings in the aspects of root activity, strong seedling indexes, planted yield and the like.

Description

technical field [0001] The invention relates to a method for cultivating strong tomato seedlings by mixing choline chloride and prohexadione calcium, which belongs to the field of agricultural technology. Background technique [0002] Tomato plug seedlings have been widely used in production. The traditional plug-in seedling raising technology is exactly to use peat, vermiculite, perlite and other lightweight materials as substrates, and plug-in trays with different holes as containers. Its characteristics are: one hole for one grain when sowing, one hole for one plant when seedlings grow, each seedling has an independent space, water and nutrients do not compete with each other, the age of seedlings is 10 to 20 days shorter than that of conventional seedlings, and the seedlings grow quickly , no soil-borne diseases, and the root lumps of seedlings are not easy to disperse, the root system is complete, the roots are not damaged after planting, the seedlings are slowed down ...
