Abstract
The present invention discloses a protection agent for cotton seedling. It is made up by using soil water-retaining agent, carbendazim, ammonium carbonate, calcium superphosphate and potassium chloride through a certain preparation process. In said cotton seedling protection agent the soil water-retaining agent is a cross-linked polyacrylamide and potassium polyacrylate salt copolymer, and its content is 14-19%, carbendazim content is 20-24%, ammonium carbonate content is 14-19%, calcium superphosphate content is 30-37% and potassium chloride content is 9-14%. Said invention also provides the concrete application method of said cotton seedling protection agent.
Description
Technical field
The present invention relates to a kind of net bottom plastics cave dish and carry out the protectant of emerging that raising seedling of cotton is used, belong to the agriculture cultivation technology field.
Background technology
Current, China whole southern cotton region cotton mainly adopts the nutrition bowl seedling transplanting mode to plant, and this seedling raising manners need prepare about diameter 7cm, the cylinder type nutritive cube of height 8-10cm, the worker employed in a plant nursery is many, and labour intensity is big, and the blue or green strong labour in incompatibility rural area is to the situation of city transfer.Therefore having produced soilless substrate grows seedlings the root-naked transplanting technology.The used plastics cave dish of soilless substrate seedling growing process is the common plastics cave dish that an aperture (about diameter 0.5cm) is only arranged at the bottom, the carrier of growing seedlings is soilless substrate (being mainly vermiculite, mica group material), only by aperture and moisture exchange and nutrient on every side, can not satisfy the needs of emerging with cotton seedling growth, after planting needing to cause frequent keeping the skin wet and nutrition, could germination and emergence and the growth of cotton seedling.Though the net bottom plastic container seedlings technology can absorb soil moisture and nutrition by net bottom, still has the risk that can not satisfy germination and emergence.And the net bottom point disk seedling growing still is that carrier is grown seedlings with soil, has the risk of anthrax, germ harm such as upright withered.The popularization of net bottom plastic container seedlings technology, be badly in need of wanting a kind of protectant, solve three key issues in the seedling raising process: the one, moisture still has the problem of shortfall risk in the dish of solution cotton seed germination and emergence stage cave, so just need not keep the skin wet in the germination and emergence process; The 2nd, guaranteeing has the prescribing adequate nutrition supply in the dish of cave; The 3rd, prevent infecting of germ in the germination and emergence process.
Summary of the invention
Purpose of the present invention is exactly that water deficient, nutrition are not enough, the problem of infection process at taking place easily in the existing raising seedling of cotton process; provide a kind of emerge in process moisture abundance in the dish of cave, nutrition of cotton germination that can make abundant, prevent the protectant of emerging of the cotton net bottom plastic container seedlings of infection process.
The technical scheme that the object of the invention realizes is; the protectant of emerging of cotton net bottom plastic container seedlings; it is characterized in that being hybridly prepared into by water-loss reducer of soil, carbendazim, carbon ammonium, superphosphate and potassium chloride; its percentage by weight is: water-loss reducer of soil 14-19%; carbendazim 20-24%; carbon ammonium 14-19%, superphosphate 30-37%, potassium chloride 9-14%.
Described water-loss reducer of soil is cross-linked polyacrylamide and polyacrylic acid potassium salt copolymer.
Selection science of the present invention, reasonable mixture ratio is composited by the agricultural chemicals of water-loss reducer of soil, anti-seedling diseases and desired nutritional are mixed by the suitable concentration of germination and emergence stage requirement.Water-loss reducer of soil, the carbendazim consumption in the protectant of emerging is all to be 0.1% to be foundation with its optium concentration of using in soil separately; and according to the point disk seedling growing soil loading amount; the two surplus mutually requirement that obtains; carbon ammonium, superphosphate, potassium chloride requirement then are according under the area condition of identical land for growing field crops; the soil amount that the net bottom point disk seedling growing needs is the percentage of conventional nutritive cube soil, remains to obtain with carbon ammonium, superphosphate, the potassium chloride amount of application for preparing conventional nutritive cube again.Through experimental examination, under the net bottom plastic container seedlings condition, the seedbed in every mu of land for growing field crops is used for sowing cotton seed and can reaches anti-seedling diseases after using this emerge protectant 180g and soil mixing, can keep the purpose of earth moisture and assurance germination and emergence nutrition supply again.Because these materials all are material commonly used in the agricultural production, can normally on producing, use, can not produce harmful seondary effect.
Net bottom plastic container seedlings is used the protectant of emerging and is mainly contained the following aspects beneficial effect:
(1) keeps soil moisture in the germination and emergence stage cave dish, go out full stand, tidy seedlings output.
Comparative trial showed in 2006; sowing on April 18; April 20 was measured; adding protectant cave dish soil moisture content of emerging is 36.2%, do not add only 30.5%, when broadcasting back 7 days and emerging; adding protectant cave dish soil moisture content of emerging is 34.6%; emergence rate is 92.3%, the cave that do not add dish soil moisture content only 29.1%, emergence rate 72.6%.Test in 2007 further shows, sowing on March 29, and adding the protectant processing soil moisture content of emerging when broadcasting back 8 days neat seedlings is 31.8%, and emergence rate is 90.2%, and contrast is 77.3%.
(2) significantly reduce the cotton seedling incidence of disease.
Test in 2006 shows, sowing on April 18, and when the 1st true leaf flattened, adding the protectant of emerging, to handle disease seedling rate be 9.2%, what do not add is 32.3%.Test in 2007 further shows, sowing on March 29, and when the 1st true leaf flattened, adding the protectant of emerging, to handle disease seedling rate be 7.6%, what do not add is 27.3%.
(3) cotton seedling stalwartness.
Test in 2006 shows, add the protectant of emerging when handling the neat seedling of cotton seedling plant height be 5.6cm, cotyledon is long to be 3.8cm, wide is 2.5cm; The contrast plant height is 5.1cm, and cotyledon is long to be 3.5cm, and wide is 2.3cm.Test in 2007 shows, adds the protectant cotton seedling of germination and emergence plant height, cotyledon size when neat seedling and all is better than contrast.
Embodiment
The protectant of emerging is the complexing agent that is mixed; by percentage by weight is 16.6% water-loss reducer of soil (cross-linked polyacrylamide and polyacrylic acid potassium salt copolymer), 22.2% carbendazim, 16.7% carbon ammonium; 33.4% superphosphate, 11.1% potassium chloride is through being mixed and made into.The protectant of emerging is used for cotton net bottom plastic container seedlings, and every mu of seedbed total amount 180g gets final product.
The ten thousand beautiful tests of Yangzhou University agriculture and animal husbandry field poplar show, emerge protectant application and contrast (do not use and compare), and planting percent improves 21%, and the cotton seedling seedling diseases incidence of disease descends 19.6%, and cotton seedling increases 1.2cm during transplanting.Blade obviously increases, and becomes that the seedling protectant has that good promotion is emerged, diseases prevention and the cotton seedling growth of promotion effect.
Claims (2)
1, a kind of protectant of emerging of cotton net bottom plastic container seedlings; it is characterized in that being hybridly prepared into by water-loss reducer of soil, carbendazim, carbon ammonium, superphosphate and potassium chloride; its percentage by weight is: water-loss reducer of soil 14-19%; carbendazim 20-24%; carbon ammonium 14-19%; superphosphate 30-37%, potassium chloride 9-14%.
