Abstract
A method for applying alachlor in paddy rice field to prevent and eliminate weeds is disclosed. The method for applying the mixture of alachlor, chemical fertilizer and other herbicides in the paddy rice field is also disclosed. Its advantages include high effect and promoting growth of rice.
Description
What the present invention relates to is a kind of method of using the alachlor management of weeds in paddy field.What more specifically, the present invention relates to is the method for using the alachlor management of weeds of effective dose transplanting rice Tanaka.The invention still further relates to the mixture that uses alachlor and chemical fertilizer or other weed killer herbicide at paddy field, thus management of weeds and promote the method for paddy growth effectively.
Alachlor (alachlor) is a U.S. Monsanto Company in the weed killer herbicide product of exploitation in 1966, is 48% drag-line missible oil in China's registration at present.The alachlor of domestic production is mainly 43% missible oil.Alachlor be before the amide-type selectivity bud and bud after early stage weed killer herbicide.Generally use in dry land, general per hectare consumption is the 1680-4480 gram.Control soybean, peanut, vegetables and corn ground weed.
The inventor has carried out detailed research to the use of alachlor, is surprised to find that alachlor uses on paddy field, can prevent and kill off paddy field grassy weed and part broad leaved weed.Suitably select the usage amount of dispenser phase and medicament, prevent the generation of poisoning all rightly, improve the output of paddy rice, and reduce the use cost of weed killer herbicide.Finished the present invention thus.
The invention provides a kind of method of in paddy field, using the alachlor management of weeds.
Particularly, the invention provides the method for using the alachlor management of weeds of effective dose transplanting rice Tanaka.
More specifically, the invention provides the mixture that uses alachlor and chemical fertilizer or other weed killer herbicide at paddy field, thus management of weeds and promote the method for paddy growth effectively.
Alachlor uses the usage amount of controlling weeds to change in very wide scope according to conditions such as the soil in the kinds of the kind of paddy rice, weeds, rice field and weathers at paddy field.The general usage amount of alachlor is a 7.5-450 gram/hectare active ingredient, preferred 30-240 gram/hectare active ingredient, more preferably 60-120 gram/hectare active ingredient.
Alachlor can use management of weeds at rice seedling bed and transplanting rice Tanaka, preferably uses transplanting rice Tanaka, is applicable to any rice varieties.
Alachlor can also with chemical fertilizer mixing dispenser, or with other weed killer herbicide mixing dispenser.Chemical fertilizer can be inorganic fertilizer and an organic manure commonly used in the paddy field.Inorganic fertilizer wherein comprises the composite fertilizer of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and various plants nutritive element.Other weed killer herbicide comprises can mix the multiple weed killer herbicide that uses with alachlor.The weed killer herbicide of preferred control broad leaved weed, for example sulfonylurea herbicide bensulfuron-methyl, pyrazosulfuron etc.Most preferably in the mix preparation of mefenacet+bensulfuron-methyl+alachlor that our company develops, use.The weed killer herbicide that can use with comprises that phonetic grand, the ethoxysulfuron of oxadiargyl, triazolone grass ester, miaow grass amine, tetrazolium, halosulfuronmethyl, gold autumn, imidazoles sulphur are grand, bensulfuron-methyl, pyrazosulfuron, Sha Duofu, Han Letian and mefenacet, can the two be used with arbitrarily, also can three or multiple using with.
The alachlor that uses among the present invention can be former medicine or its conventional preparation, for example: missible oil, wetting powder, granule or water-dispersible granules etc.Above-mentioned preparation can adopt conventional preparation to prepare by formulation method conventional in this area.
Explain the present invention below by concrete drug effect embodiment.
The comparative trial (potted plant) of embodiment 1 rice safety
The confession of adopting in this test rice varieties that tries the water is east farming 416.With the rice seedling rice transplanting the test with little basin in, 5 strain rice seedlings in every basin.After the rice transplanting 6 days, paddy rice is delayed seedling, and mixed soil evenly spreads fertilizer over the fields medicament, keeps 3 centimetres of water layers.Dosage is per hectare alachlor 60,80,100 and 120 grams, butachlor 1000 grams.And establish not dispenser contrast, each is handled and repeats 4 times.Result of the test sees following table 1 for details.
Table 1: rice safety test
| Medicament | Consumption (g/ha) | Plant height (centimetre) | The basin effective tiller | Output (gram) |
| Alachlor | ????60 | ????100 | ?????20 | ????400 |
| Alachlor | ????80 | ????99 | ?????21 | ????420 |
| Alachlor | ????100 | ????101 | ????21.5 | ????435 |
| Alachlor | ????120 | ????99.5 | ?????22 | ????430 |
| Butachlor | ????1000 | ????98.5 | ????19.5 | ????380 |
| Contrast | ????99 | ?????21 | ????420 |
As can be known, the alachlor of various dosage does not all have influence to plant height, effective tiller and the output of paddy rice from above-mentioned test.
The comparative trial (potted plant) of embodiment 2 rice safeties
Adopt the method identical, in the poisoning effect of alachlor, Acetochlor, isopropyl methoxalamine and the butachlor of rice seedling bed comparison same dose to paddy rice with embodiment 1.
Result of the test proves that Acetochlor is the heaviest to the paddy rice injury; Next is different third to separate careless amine, and that alachlor and butachlor are handled is the safest, no poisoning generation.
Embodiment 3 alachlors control paddy field weed comparative trial (field efficacy) test method
The confession of adopting in this test rice varieties that tries the water is east farming 416.After the rice seedling rice transplanting 6 days,, manually spread fertilizer over the fields medicament in conjunction with striking root fertilizer.Be about to add low amounts of water in the medicament, mix in urea, stir, artificial hand spreads.Keep 4-5 centimetre of water layer, dosage is per hectare alachlor 60,80,100 and 120 grams, butachlor 1200 grams.Not dispenser artificial weeding is contrast, and each handles 200-400 square metre, does not establish repetition.Result of the test
(1) herbicidal effect: after the dispenser 10 days, investigation removed the barnyard grass effect when 30 days and rice harves.Except that alachlor 60 gram preventive effect when the rice harves is 95%, every this investigation of other each dosage is 100%.Butachlor treatment region effect is poor slightly, is 90-94%.Alachlor and butachlor are all undesirable to perennial weed pondweed and sedge weed preventive effect.
(2) rice yield: effective yield is that alachlor is handled 5000-6000 kilogram/hectare, and butachlor is treated to 4900 kilograms/hectare, and manual weeding is 5750 kilograms/hectare.
To sum up state as can be known, the various dosage control of alachlor rice transplanting field barnyard grass natural plant height effect, to rice safety, increase yield significantly, the grass spectrum suits and the herbicide mixture of preventing and treating broad leaved weed in order to enlarge extremely.
Embodiment 4 alachlors are mixed with 48% alachlor missible oil and mefenacet and bensulfuron-methyl 30% wetting powder with other herbicide mixture test (1), every mu northern area with 60 the gram, 80 the gram, 120 the gram, controlling weeds effective, no poisoning takes place.(2) 30% mefenacets+bensulfuron-methyl+alachlor effervescent herbicide for paddy field before paddy field is inserted, insert the back and test.Every mu of medication of northern area 60 grams, every mu of medication of southern area 30 grams, control efficiency is generally effective with mefenacet+bensulfuron-methyl than single, and does not have the poisoning generation.
