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 PlantHormone 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 in particular relates to a rice culture solution and a rice cultivation method. Adding a certain amount of melatonin into the rice culture solution solves the difficult technical problem of further improving the rice yield. Adding melatonin to the rice culture solution can promote significant changes in the growth and development process of rice, including promoting the increase of rice biomass and promoting the elongation of the first tillerbud and the second tillerbud. Melatonin can also relieve the inhibitory effect of higher concentrations of amino acids on rice growth and tillerbud elongation. Melatonin and the hydroponic solution containing melatonin can be applied in the agricultural practice of rice cultivation, thereby effectively increasing the yield of rice.
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 capitaarable 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, paniclegrain number and thousand-grain weight (Sakamato T, Matsuoka M. Identifying and exploiting grain yield genes in rice[J].CurrOp...
