Inner several test cold resistance of turfgrass


Quality of Chen Shaojie. Chen Linsong 『1. Ningbo Agricultural Technology Extension Station. Ningbo, Zhejiang 315012; 2. Agricultural Technology Extension Station, Ninghai County, Zhejiang Ninghai 315600) Abstract: Application of cucumber production The results showed that nutrition bowl leap the gap covered with a commercial organic fertilizer for seedlings. Seedling of vegetables have good moisture and increase soil fertility, seedling role, should be widely applied. Key words: nutrition bowl; nursery; fillings; Quality in Classification - ~: $ 642.2 Document code: B Article ID :1007-0907 (2009) 02--0065-01 bowl is a grass peat, lignin as the main raw material. Scientific formula, a new type of compression molding pot seedling nutrition, vegetable seedlings in Ningbo City, the application of nutrition in the rapid development of the cylindrical bowl is oblate, the seedbed on the arrangement between the bowl after bowl and still leave large gaps. Nursery water during the more difficult. Will affect the growth of seedling roots. This study aims to ask different filler bowl contrast, master bowl filler between the different effects on seedling quality. Large area for the future use of the nursery pot to provide the technical basis Nutrition Materials and methods 1.1 l test material for the test varieties of vegetables cucumber nutrition Jinyou No. l 6cm diameter bowl of Bo asked to put nutrition soil, organic fertilizer at the end,[link widoczny dla zalogowanych], sawdust powder 3 3 ways to deal with. Filler to hold the control l (ck), the self-nutritive soil 8cmx8cm plastic bowl as the control 2 (ck,). 1.2 Test methods Test is located in Ninghai County of Ningbo City, Green Castle, the base for vegetable cooperatives. Before planting a variety of nutritional bowl according to their requirements. Neatly placed in the nursery bed and were irrigated. Sowing to l2 months 27E1. Germination when the seeds have been planted roots down. Prefabricated flat on the nutrition seed planting hole edge of the bowl and light pressure. Nutritive soil after sowing cover wet and dry straw, and then tile film. Then take the small shed covering film insulation. After emergence of straw and plastic film in time to remove, cover Small Shed membrane holding nursery. Small Shed membrane during low-temperature insulation blanket coverage. To ensure safety during the winter nursery pot and vegetables based on nutritional status of the seedlings dry. Sunny afternoon in the warm water with a storage shed. 3d stop watering before transplanting and hardening 2 Results and analysis 2.1 Press seedling field performance of 29 January 2008. That the quality of cucumber seedling before transplanting study, the use of matrix nursery seedling quality nutritional bowl nutritive soil than plastic bowl (ck) is good; same matrix bowl nursery. Placed between the bowl and hold objects than objects as well. Bowl is also placed between substrate material on, he put mortar between the end of the seedling quality organic fertilizer for the best. Followed by the bowl placed between nutrition soil. Is among the worst bowl put sawdust powder. Analysis of the reasons is the matrix placed between the cover of the bowl. Bowl of water be maintained between the seedbed. Fertilizer supply to normal seedlings, seedbed microclimate conditions are good. Enabling the growth of seedlings. Between the bowl and hold objects, because there are many gaps sunny bowl asked fast evaporation, relative humidity lower beds, a small deterioration of weather conditions, affecting the absorption of seedlings and the use of fertilizer. Therefore,[link widoczny dla zalogowanych], the poor quality seedlings. Covering the same is also due to the release put the number of properties directly affect the nutritional quality of seedlings (Table 1).. Table 1 Matrix nutritional bowl of cucumber seedling quality education inspection results Cocoon Yield Yield 2.2 bowl placed between the situation of organic fertilizer to the end of the highest yield. Followed by nutritive soil placed between the bowl again, and hold objects between a bowl and put bowl of sawdust between the powder,[link widoczny dla zalogowanych], yield the lowest nutritive soil plastic bowl (ck:) (Table 2). Table 2 Matrix nutritional bowl of cucumber seedling production Summary of Survey Results 3 The results showed that Compression type matrix nutritional bowl in the Received Date :2009 -02-25 cover seed after sowing irrigated. The gap between the bowl and the bowl surface covered with a commercial organic fertilizer for seedlings, seedling of vegetables have good moisture and increase soil fertility,[link widoczny dla zalogowanych], seedling role. Worthy of future large scale production applications. (Editor Wu Yunxia) standard and the determination of biochemical indicators. Both the use of tissue conductivity method and determination by the degree of injury soluble sugar content,[link widoczny dla zalogowanych], determine the cold tolerance of different grass species lethal temperature (ie extreme temperature) and a variety of hardy grass in order: hard fescue> Kentucky bluegrass> fescue> Festuca> hair lemma red fescue> Portugal stems creeping bentgrass> perennial ryegrass> white clover. And that the order of the winter with the visual performance of the basic match. This is the right choice for us to grow a suitable lawn grass in the region provide a more reliable theoretical basis.
