Abstract
The present invention relates to a leaf-protecting agent. It is made up by using 8-hydroxyquinoline, polyethylene glycol, alpha-naphthylacetic acid and water according to a certain mixing ratio and adopting a certain preparation method. Said leaf-protecting agent can be used for spraying aerial part of plant offspring, organ or plant before which are transplanted or after which are transplantea, and said invention can protect its leaf, and can promote its underground portion rootage and growth of root system to raise transplanting survival rate.
Description
Technical field
The invention belongs to agriculture field, relate to a kind of leaf-protecting agent that plant seedlings, organ or plantlet of transplant front and back spray overground part that is used for.To the crop nursery stock flowers that have soil or soilless-cultivated seedling to transplant, can reduce and transplant rising dehydration of its overground part of back and physiology consumption and promotion and plant the back and protect leaf and return seedling, use the present invention can help to improve transplanting survival rate and the back seedling-slowing stage is planted in shortening.
Background technology
Recent two decades comes, and the constantly progressive and development of the production culture technique mode of various forests, crop and fruit and vegetable makes every agrotechnique and product obtain sufficient development.For example the seedbed seedling transplanting technique is exactly the advanced culture technique that can impel plant to send out precocity, raising output, enhancing quality soon, it can also economize the land resource, and alleviates crops for rotation pressure, enriches cropping system, save to use and plant, thereby brought remarkable economic efficiency and social benefit.The utilization in the production cultivation of this technology is very extensive and diversified.At present the ripe or multiple cropping degree in some areas one carries out seedling raising and transplanting throughout the year, for example on crops as paddy rice, corn, rape, cotton etc., and on various vegetables and flowers, use for many years.Seedling raising and transplanting has formed the agrotechnique of a kind of China characteristic.
But the subject matter that seedling raising and transplanting exists is transplanting survival rate and returns seedling fast, and more particularly because of self characteristics is later than the plant that returns seedling after planting, it is big to show as overground part wilting degree after the transplanting, and functional leaf easily comes off; Underground part root of hair difficulty, root growth is slow.Thereby form low transplanting survival rate and long seedling-slowing stage.At present, a lot of explorations and research have been carried out at these problems scientific research person.Growing seedlings of carrier for example arranged, and the loss of root system was few when protection was transplanted; Perhaps carrier-free is grown seedlings and carry out the processing of plain rooting promoter in strong sprout, improve the slow seedling ability in back of planting.Taking root after the transplanting is the key that survives gentle seedling, after planting, plant must keep a suitable root/shoot ratio but transplant, and the physiology consumption that the excessive rising dehydration that functional leaf is prone to when transplanting plant and transplanting on the one hand causes and wilt or come off, root system can not in time delay seedling absorption soil moisture and satisfy rising dehydration on the other hand.Given this, need a kind of leaf-protecting agent protection blade and suppress rising and promote the underground part root of hair, keep suitable root/shoot ratio, promote behind the plant transplantation transplanting survival rate to improve and return seedling fast.
Summary of the invention
The present invention is intended to the common harmony effect by several chemical agents, form a kind of mixing material, after plant shoot sprayed, after a related substances part was partially absorbed by plant leaf blade and other, a part was had an effect with plant leaf blade and other acrial parts.Therefore after plant is used this product invention, can on blade and other positions, form a kind of chemoproection film of compound molecule structure, reduce the rising dehydration of plant shoot, and strengthen the defence opposing of plant to sick worm or adverse circumstance, what the physiology consumption of defencive function leaf caused simultaneously comes off; Can also promote its underground part root of hair and root growth.Particularly carrier-free or the transplanting plant seedlings and the organ thereof of carrier less, help to improve transplanting survival rate and return seedling fast, recover blade normal physiological complex functionality ahead of time, promote root growth, the enhancing plant absorbs nutritive element, strengthens to adapt to natural environment.
Preparation of the present invention is finished by following scheme, it is characterized in that forming by oxine, polyethylene glycol, a-methyl, water formulated in combination, its parts by weight are 1～5 part of oxine, 5～10 parts of polyethylene glycol, 0.01～0.5 part of a-methyl, 84～94 parts in water, each substance weight proportioning is oxine in scope: polyethylene glycol: the a-methyl: water is 1: 1～10: 0.002～0.5: 16.8～94.The optimum weight of each component of this product is 3 parts of oxines, 7 parts of polyethylene glycol, 0.05 part of a-methyl, 89.95 parts in water.
Leaf-protecting agent of the present invention adopts following method preparation, earlier each material is heated 70 ℃～90 ℃ by the water that proportioning takes by weighing 1/2nd to 3/4ths, polyethylene glycol is added to wherein dissolving fully, add oxine after cooling, with remaining water-soluble separate the a-methyl after, two parts of solution are stirred promptly obtain this product at last.
The using method of leaf-protecting agent of the present invention is characterized in that spraying the plant overground part, also can smear the plant exposed parts.
Specific embodiments
Now join 2kg leaf-protecting agent of the present invention according to the optimum weight mix proportion scheme that provides in this specification, promptly take by weighing earlier oxine 0.06kg, polyethylene glycol 0.14kg, a-methyl 0.001kg, water 1.799kg respectively.Earlier water is got about 1/2nd and be heated to 80 ℃, polyethylene glycol is dissolved in the water fully, after the normal temperature cooling, add oxine 0.06kg again, obtain mixed liquor, with dissolving of a-methyl and adding mixed liquor, stir the leaf-protecting agent that promptly obtains feature of the present invention with remaining water.Be used for vegetables, cotton and the flowers of seedling raising and transplanting, transplanting survival rate has reached 96.4%～100%, does not more use the treatment measures transplanting survival rate of this product to improve 5%～60%; Seedling-slowing stage shortens 1～3 day.
Claims (4)
1, a kind of leaf-protecting agent that is used for spraying before and after plant seedlings, organ or the plantlet of transplant overground part, it is characterized in that it being to form by oxine, polyethylene glycol, a-methyl, water formulated in combination, its parts by weight are 1～5 part of oxine, 5～10 parts of polyethylene glycol, 0.01～0.5 part of a-methyl, 84～94 parts in water, each substance weight proportioning is oxine in scope: polyethylene glycol: the a-methyl: water is 1: 1～10: 0.002～0.5: 16.8～94.
