Abstract
The invention discloses a method for immersing corn seeds by combining a rare earth element lanthanum with temperature variation and belongs to the field of common breeding of plants. The method comprises the following steps: firstly, preparing a rare earth element lanthanum working solution with the concentration of 300ppm; putting corn seeds into a seed bag; after disinfecting at 50 DEG C for 10 minutes, immersing the seeds into the rare earth element lanthanum working solution according to the ratio of the mass of the seeds to the volume of the rare earth element lanthanum working solution of 1 to 5; and performing slow temperature variation treatment for 1 day at 20 or 30 DEG C; and putting the treated corn seeds into a germination box containing sand to germinate for 10 days at a constant temperature of 25 DEG C (12 hours in light and 12 hours in dark).
Description
Technical field
Rare-earth elements of lanthanum, in conjunction with a method for alternating temperature soaking corn seed, belongs to plant conventional breeding field.
Background technology
Corn is a kind of important grain, economy and forage crop, and purposes is wide, and demand is large, occupies an important position in national economy.Therefore, improve corn yield for guarantee national food security, promotion livestock breeding and rural economic development, increase peasant economy income and there is important effect.At present, domestic corn planting adopts the mode of drilling and bunch planting, and is directly main mainly with seed down, the defect of the method is seed sprouting, neat seedling Time Inconsistency, and is short of seedling phenomenon seriously, the huge trouble to Maize Production band.Therefore, improve full stand rate, full stand rate and strong sprout rate be the basis ensureing that corn yield increasing increases income.
Summary of the invention
Rare-earth elements of lanthanum, in conjunction with a method for alternating temperature soaking corn seed, is characterized in that, include the preparation of rare-earth elements of lanthanum working solution, sterilization, seed immersion, slowly intermittent warming, sprouting in described method, concrete operation step is as follows:
1. rare-earth elements of lanthanum working solution preparation: precise weight is be settled to 10L after the rare earth element lanthanum chloride running water of 3g dissolves, and is the rare-earth elements of lanthanum working solution of 300ppm;
2. sterilize: warm water seed being placed in 50 DEG C is sterilized 10min;
3. seed soaks: according to seed quality: the ratio of rare-earth elements of lanthanum working solution volume=1:5, be soaked in by seed in the rare-earth elements of lanthanum working solution of 300ppm;
slow intermittent warming: according to 25 DEG C/2.5h, 30 DEG C/7h, 25 DEG C/2.5h, 20 DEG C/12h carries out intermittent warming 24h;
sprout: the seed after alternating temperature is placed in the sterilized germination box containing river sand and sprouts, sprouting condition is constant temperature 25 DEG C of 10d (12h light, 12h are dark).
The invention has the advantages that from the viewpoint of full stand, Qi Miao, strong sprout etc., with the hormone of low concentration (as IAA, IBA, GA etc.), rare earth element (lanthanum, cerium etc.), trace element (boron fertilizer, zinc fertilizer etc.) etc. for soaking working solution, immersion treatment is carried out to corn seed.The object promoting seed simultaneously stability hormone, trace element, rare earth element and moisture can be reached by the method, realize improving full stand rate, full stand rate and strong sprout rate beneficial effect.
embodiment:
Below in conjunction with specific embodiment, the present invention is conducted further description.
Embodiment
Rare-earth elements of lanthanum, in conjunction with a method for alternating temperature soaking corn seed, is characterized in that, include the preparation of rare-earth elements of lanthanum working solution, sterilization, seed immersion, slowly intermittent warming, sprouting in described method, concrete operation step is as follows:
1. rare-earth elements of lanthanum working solution preparation: precise weight is be settled to 10L after the rare earth element lanthanum chloride running water of 3g dissolves, and is the rare-earth elements of lanthanum working solution of 300ppm;
2. sterilize: warm water Zheng Dan 958 seed being placed in 50 DEG C is sterilized 10min;
3. seed soaks: according to seed quality: the ratio of rare-earth elements of lanthanum working solution volume=1:5, be soaked in by seed in the rare-earth elements of lanthanum working solution of 300ppm;
slow intermittent warming: according to 25 DEG C/2.5h, 30 DEG C/7h, 25 DEG C/2.5h, 20 DEG C/12h carries out intermittent warming 24h;
sprout: the seed after alternating temperature is placed in the sterilized germination box containing river sand and sprouts, sprouting condition is constant temperature 25 DEG C of 10d (12h light, 12h are dark).Compare with the seed of intermittent warming with without element, full stand rate and full stand rate all improve more than 5.8%.
