Embodiment 1

[0041] Example 1: Effects of Different Concentrations of Melatonin Treatment on the Growth and Development of Rice

[0042] 1. Seed soaking of rice: Soak the rice seeds with 6 / 1000 dilute nitric acid for about 6 to 8 hours. Among them, the rice seeds are ZH11 rice seeds (the seeds are all from the Plant Hormone and Nutritional Molecular Regulation Laboratory of Guizhou University).

[0043] 2. Cultivation of rice seeds: After soaking, rinse the seeds 3 to 5 times, pack them into petri dishes, add appropriate purified water, put them in an incubator for cultivation, and change the water 2 to 3 times a day regularly.

[0044] 3. Hydroponics: When the rice grows uniformly to the 3-leaf stage, add 18L of common culture medium to the culture box, and then move the rice to the culture box for cultivation, and set up 6 culture boxes. The preparation of ordinary culture solution is a routine technical means for those skilled in the art, and is prepared with reference to literature me...

Embodiment 2

[0049] Embodiment 2: The effect of amino acid compound melatonin treatment on the growth and development of rice

[0050] The soaking steps of rice in this embodiment, the cultivation steps of rice seeds and taking materials and measuring the biomass are the same as in Example 1.

[0051] 3. Hydroponics: When the rice grows uniformly to the 3-leaf stage, add 18L of common culture medium to the culture box, and then move the rice to the culture box for cultivation, and set up 4 culture boxes.

[0052] 4. Melatonin treatment: After 3 days of hydroponic cultivation, the seedlings have basically adapted to the cultivation in the culture box, and respectively added melatonin 0 μmol / L, Lys 1.5mmol / L+Arg 0.5mmol / L, melatonin 1μmol / L, Lys 1.5mmol / L+Arg0.5mmol / L+Melatonin 1μmol / L.

[0053] From the rice seedlings in the above several different treatments and controls, randomly pick a seedling between the average plant heights of each treatment, put it on the black cloth and connect it...

Abstract

The invention belongs to the technical field of plant cultivation biology, and particularly relates to a rice culture solution and a rice culture method. A certain amount of melatonin is added into the rice culture solution, so that the technical problem of high difficulty in further improving the unit yield of rice is solved. Melatonin is added into the rice culture solution, so that the growth and development process of rice can be promoted to be obviously changed, including promoting the increase of rice biomass and promoting the elongation of the first tillering bud and the second tillering bud. Melatonin can also relieve the inhibition effect of amino acid with higher concentration on rice growth and tillering bud elongation. The melatonin and the hydroponic solution containing the melatonin can be applied to agricultural practical activities of rice cultivation, so that the unit yield of rice is effectively increased.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation biology, and in particular relates to a rice culture solution and a rice cultivation method. Background technique [0002] "Food is the most important thing for the people, and rice is the first food." Rice has always played a dominant role in my country's grain production and consumption. Due to social and economic development and urban and rural construction needs, my country's rural arable land area and per capita arable land area are gradually decreasing, and the increase of rice production is increasingly dependent on the increase of per unit yield. Therefore, increasing the per unit yield of rice has become an important goal of increasing rice production. Rice yield per unit area is mainly composed of three basic elements: effective panicle number, panicle grain number and thousand-grain weight (Sakamato T, Matsuoka M. Identifying and exploiting grain yield genes in rice[J].CurrOp...
