Embodiment 1

[0029] Embodiment 1, corn (interactive plant) and cotton (target plant) interactive seedling raising method

[0030] (1) Implementation plan:

[0031] Treatment A: On March 15, one corn seed (interactive plant) and one cotton seed (target plant) were sown in the hole of the seedling tray filled with 2 / 3 soil at the same time, and the thickness of the upper cover was about 2 cm after sowing. Then put it into the shed covered with agricultural film, and use the sodium indole acetate aqueous solution with a concentration of 30mg / Kg as the plant root accelerator to keep the soil humidity between 60%-65%. After the plants emerge, use a nutrient solution containing N, P, and K nutrients (containing 0.01% urea and 0.01% potassium dihydrogen phosphate, and the rest is water) to keep the soil humidity at about 60%-65%, until the height of the corn seedlings exceeds that of cotton When the seedlings are high, spray with 0.05% (mass percentage concentration, the same below) cotton fie...

Embodiment 2

[0038] Embodiment 2, rapeseed (interactive plant) and corn (objective plant) interactive seedling raising method

[0039] (1) Implementation plan:

[0040] Treatment A: On March 15, one rapeseed (interactive plant) and one corn seed (target plant) were sown in the hole of the seedling tray filled with 2 / 3 of the soil at the same time, and the thickness of the upper cover was about 2cm after sowing. After that, put it into the shed covered with agricultural film, and use the indole butyric acid aqueous solution with a concentration of 10 mg / Kg as the plant root accelerator to keep the soil humidity between 60% and 65%. After the plants emerge, use the nutrient solution (the composition of the nutrient solution is the same as that of Example 1 to treat A) to keep the substrate humidity at about 60%--65%. Spray dicamba and harden the corn seedlings. Spray the second herbicide about 7 days before transplanting, continue hardening until seedlings rise, and gently lift the corn s...

Embodiment 3

[0045] Embodiment 3, wheat (interactive plant) and watermelon (objective plant) interactive seedling raising method

[0046] (1) Implementation plan:

[0047] Treatment A: On March 10, one seed each of wheat (interactive plant) and watermelon (purpose plant) was sown in the hole of the seedling tray filled with 2 / 3 of the soil at the same time, and the cover was covered with a thickness of about 2 cm after sowing. The soil is then placed in a shed covered with agricultural film, and the indole butyric acid aqueous solution with a concentration of 10 mg / Kg is used as a plant root accelerator to keep the soil humidity between 60% and 65%. After the plants emerge, use the nutrient solution (the composition of the nutrient solution is the same as that of Example 1 to process A) to keep the soil moisture at about 60%-65%. When the height of the wheat seedlings exceeds the height of the watermelon, use 0.05% of the watermelon selective stem and leaf herbicide Spray sethoxydim, st...

Abstract

The invention relates to a seedling culture method by using interaction of two plant seedlings, which comprises the following concrete steps: seeding the seeds of one kind or two or more kinds of plants (interaction plants) and the seeds of a plant (target plant) which is planted in a seedling transplanting way together in the same hole of a seedling tray; after the seeding, covering the hole with a matrix; putting the hole in an agricultural film tunnel or greenhouse; after the seedling of the plant emerges, uncovering the film or opening the tunnel to train the seedling until the plant root system combines the matrix into a tight bowl body; removing the interaction plants by use of a selective herbicide or preventing jointing of the interaction plants by use of vernalization; and then lifting and transplanting the seedling. The invention enhances the strength of the bowl body by use of the root system of the interaction plants so as to prevent easy loosening of the bowl body, shortens the rejuvenation period after planting and realizes low production cost.

Description

technical field [0001] The invention belongs to the technical field of agriculture and forestry, and in particular relates to a method for two plant seedlings to grow seedlings through mutual interaction, which uses the interaction between plants to eliminate or reduce the secretions in the root system of plants that are unfavorable to their own growth and improve the air permeability of the substrate , and make the root system of the target plant, the root system of the interacting plant and the matrix form a better netted matrix body. Background technique [0002] Plant seedlings, especially industrial seedlings, often have insufficient adhesion between the pot body and the root system, making the pot body easy to disperse. If it needs to be transported, it can only be transported with a reel, or transplanted with bare roots, which will either increase the cost of the seedlings, or cause a long seedling period. [0003] At the same time, due to the different autotoxicit...
