Abstract
The invention relates to a watermelon yield increasing and sugar increasing conditioner and a use method thereof. The conditioner is 20mg/L-500mg/L of glycosaminoglycan water solution with the molecular weight of 300KDa-600KDa. The spraying treatment is carried out on leaf surfaces in 7 days after a watermelon is pollinated. The conditioner is simple to prepare, convenient to use, low in cost and obvious in effect, has the time-saving and labor-saving effects, integrates double effects of yield increasing and sugar increasing and lays the foundation of good quality and high yield of the watermelon.
Description
Technical field
The invention belongs to plant regulation agent research and development and application, be specifically related to a kind of increasing yield of water melons and improve sugar, the conditioner that improves quality and using method thereof.
Background technology
Watermelon is " king in melon ", and juice multi-flavor is sweet, clearly quenches one's thirst, and is good fruit in midsummer, by people are liked food.Watermelon is one of the world's ten large fruit, and its area under cultivation and gross yield are all in fruit prostatitis, the world.China is maximum in the world watermelon producing country, accounts for the more than 45% of world's area under cultivation and gross yield.According to statistics, watermelon consumption figure is at 15Kg every year on average for China city dweller, and some big and medium-sized cities are up to more than 25Kg.In annual 6 the hottest～August of summer, the supply of watermelon accounts for the more than 70% of fruit in summer market.In recent years, along with the raising of people's living standard, the requirement of local flavor, quality, year-round supply and the commodity of consumer to watermelon is more and more higher, the consumption demand of watermelon also constantly expands, cultivated area expanding day, many local watermelon crop rotations have been subject to having a strong impact on, and cause continuous cropping phenomenon more and more serious, total crop failure is caused in serious plot, and yield and quality constantly declines.
Increasing yield of water melons or increase the sweet quality chemical control technique that improves and apply more in watermelon, for example, spray Ye Mian Bao, use the sweetener such as RE microbial fertilizer, spray plant growth regulator or enlarging agent, although these methods can promote that watermelon expands, what have also has a sweet effect of certain increasing, but it is more generally to spray number of times, although the volume increase having but melon is lightly seasoned sweetless, and has certain side effect, as while spraying enlarging agent, very easily cause melon cracking, reduce commodity.Patent ZL201010147639.4 " a kind of quality improver and using method thereof that improves sugar of watermelon " and patent ZL201010147640.7 " improving quality improver and the using method thereof of sugar of watermelon ", disclose respectively and utilized the stachyose aqueous solution, the NaCl aqueous solution or NaCl and KNO
3the aqueous solution is prepared the technology of water melon sweet-increasing preparation, though can improve sugar of watermelon, without effect of increasing production, and needs repeatedly to use continuously production application inconvenience.Patent CN1175352A " application of plant growth regulator ' Inshuzhi ' in watermelon is produced ", disclose and utilized the application technology of 'Inshuzhi ' in watermelon is produced, show to spray on watermelon 'Inshuzhi ', can reach the effect that increases the yield of watermelon, improves sugariness and premature ripening, but 'Inshuzhi ' is as a kind of plant growth regulator of chemosynthesis, field application requirements is strict, its effect is decided by application concentration and period, and there is certain safety, fail large scale application in production reality for this reason always.
At present, in production, yet there are no and integrate volume increase and the watermelon selectivity technical products that increases sweet effect, be badly in need of a kind of high-quality of research and development, efficient, safe, non-harmful high performance cheap conditioner, reduce the use of chemical fertilizer, increase the yield of watermelon, and improve sugariness of water-melon, improve quality, to solve increasing production and improying productivity in watermelon production, to promoting that China's watermelon is lasting, healthy, stable development has great importance.
Summary of the invention
For the problems referred to above, the object of the invention is to: a kind of increasing yield of water melons is provided and improves sugar conditioner and using method thereof, this conditioner safety non-toxic, draw materials conveniently, with low cost, preparation is simple, drug effect is remarkable, being applied to watermelon produces, can significantly increase production and improve sugariness, reach volume increase and increase sweet double effects, overcoming the drawback that the effect existing in prior art measure unstablely, time-consuming is taken a lot of work, cost of investment is high, effect is single.
In order to solve the problems of the technologies described above, technical solution of the present invention is: this watermelon conditioner is 20mg/L～500mg/L glycosaminoglycan aqueous solution, and described glycosaminoglycan is a kind of or its different molecular weight mixture in molecular weight 300KDa～600KDa.
Above-mentioned increasing yield of water melons with the using method that improves sugar conditioner is: pollinate and within latter 7 days, use 20mg/L～500mg/L glycosaminoglycan aqueous solution to carry out foliar spray in watermelon, the 7 days repeat sprayings in interval once, each per hectare liquid consumption 300L～450L.
Compared with prior art, the present invention has following feature and advantage: (1), using water as medium, has significant environmental benefit and social benefit, is of value to the healthy of operating personnel, improves safety; (2) easy to use, simple to operate, watermelon result initial stage foliage-spray 2 times; (3) there is volume increase and increase sweet double effects, overcoming the drawback that the effect existing in prior art measure unstablely, time-consuming is taken a lot of work, cost of investment is high, effect is single; (4) raw material is easy to get, cheap, glycosaminoglycan, as natural polymer and chitin derivativ, extensively existing at natural world, is that natural world reserves are only second to the cellulosic the 2nd large natural polymer, the inexhaustible huge regenerated resources treasure-house of the mankind especially, taking it as preparation raw material, there is advantageous advantage and environment friendly; Meanwhile, utilize the glycosaminoglycan of specified molecular weight, avoid glycosaminoglycan because of the different molecular weight difference to crop regulating effect, overcome formulation products unstable and be difficult to formulate the drawback of target level of product quality.
Embodiment
The term that used in the present invention, unless there is other explanation, generally has the implication that those of ordinary skill in the art understand conventionally.
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be understood that these embodiment just in order to demonstrate the invention, but not limit the scope of the invention by any way.
