Review summary of the results and the experiment
from the study properties of soil and water sources in the growth of large pie and he found that the water is alkaline Acid Is Between 6.32 - 6.95 and soil pH is alkaline, between 6.05 - 6.58 according to reports, and at dawn of the earth's (2548 ) reported that the water plants in foreign currencies Cryptocoryne survey found in the central region and the east area is a stream of water is alkaline Acid Is Between 6.06 - 7.98 and soil pH is alkaline, between 4.3 - 7.4, and in the south found in the stream where the water is alkaline Acid Is Between 6.14 - 7.3 and soil pH is alkaline, between 5.2 - 6.7 for the hardness of the survey is located between 22 - 51 mg/L.Consistent with Rataj and Horeman (1977 ) reported that the area where the water is found Cryptocoryne balansae to more or less the hardness is a limestone mountain brook water which is very hard to analyze eagle from the object in the ground in this survey0.44 - 1.37 phosphorus that is useful is located between 5.49 - 23.43 MM/kg and Butterfish is located between 31.0 - 149.46 MM/kg.According to the report, and at dawn of the earth (2548 ) reported that water plants Cryptocoryne currency survey found in the central and eastern regions in the creek the land is eagle, as an object is between 0.41 - 6.16 phosphorus is a useful value is between 2 - 25 mg/kg.Butterfish is located between 15 - 64 mg/kg.For the proportion of soil particles from the analysis found that this is a land that has a sandy soil (Sandy Loam) and clay mixed with sand (Sandy Clay Loam) in accordance with reports of dawn and at the Earth's (2548 ) reported that water plants Cryptocoryne currencyThe land is sandy soil and clay mixed with sand (Sandy Clay Loam/Sandy Loam/Loamy Sand/Sand)
From the requirements of the water temperature of the water is different, such as last year's average around 24.1 degrees Celsius temperature of the air in an average year round 26.1 degrees Celsius, the blades he will dwell in large water source at a temperature that is not too high and not very low average value of the intensity of light in the last 25 years,650 LUX light indicates that it is necessary for the growth of the blades in accordance with the study of his large Boney (1975 ) reported that algae under the water with a light synthetic rate is in the range 20,000 - 30,000 LUX amount of oxygen dissolved in water is average around 6.5 years/L.as it is a source of water so that the water flow is a stream of water soluble oxygen is high, because the exchange of oxygen and water quantity of carbon dioxide in the air at all times in an average water year round 5.25 MM/L.which is a value that is quite suitable for the growth of higher plants water depth and turbidity of the water, there is a consistent level of water during the month of June - September, the depth 120 - 140 cm of turbidity of water 15.19 - 21.23 FTU because the rain washes down to the water flow and pressure to settle land in the water and the water has a high turbidity while during the month of December - March water level has the deep 30cm. turbidity of water 3.57 - 5.05 FTU because at the moment the level decreases in precipitation values for ammonia-nitrogen in an average year round 0.0380 MM/L. the ไตรต์ - nitrogen is average in year round 0.0049 mm/L. nitrate-nitrogen in an average year round 0.0384 mm/L.There is phosphate, i.e. Benzene 0.0241 average for the year. The.which is phosphorus nutrients, that is important to the growth of algae in freshwater sources in water sources are often in the form i.e. Benzene phosphate (orthophosphate) which Amity and spy, and the Minister of Justice (2528.) referred to the study in a foreign country,0.01 mg/L., source of water, nutrients, there are too many sources of water pollution problems that have a higher amount of phosphorus 0.6 mg/L.The survey shows that the source of water water has a relatively high amount of nutrients, adequate for the growth of water plants, especially the source of water is available on the higher the washes of nutrients, from the soil into water source when there is heavy rain
From the study of biological mass produce large and he found that the blades are biological mass production up in September (average live weight 304 grams per sq. ft.) Minimum in the month of March (average live weight 46 grams per sq. ft).(21.22 cm) and the maximum in September (41.74 cm.mass production of biological Information), so that the blades so that they conform with large values, the length of the average water in the month of March due to reduce the amount of water that he had found the beginning of the blades, etc. , that are to be on land, there is a majority of the length of the average a littleMost will be found under the water, it is the beginning of the length of the average over the period in which other country has not yet been reported in this study
