Excogitation And Application Research Of Vegetable Seedling Boxes In Full Exposure

There is now no massive intensive seed nurturing devices. Thisexperience designed one kind of full-illuminating Vegetable seed-nurturing containerfor farmers (Patent number:201020182785.6).The size:1500mm*600mm*1900mm.the other5faces of the box were coveredby PC board except the bottom layer which was covered by stainless steel board.There are6layers in the nursery box,5of which were used of nursery.the distancebetween two adjacent layers is300m.each layer could set5nursery site. There are2Temperature Humidity Sensor in one nursery box. The temperature could be regulatedbetween5to40℃and decreased by wetted pad; the fluorescent lamp couldsupplement the light.One Vegetable seed-nurturing container can nurture vegetable seedlings that meetthe need of667m2one time. Additionally, this is a1was low price and convenient. Itcan also increase the income of farmers and enhance the development of greenagriculture. This article studied the environmental index of different full-illuminatingVegetable seed-nurturing container in which hot pepper seedling werenurtured,including the number of lamps A(A1:one, illuminance1695lux；A2：twoilluminance3950lux；A3：three illuminance450lux；three levels)needed underdifferent light intensities and the square B （B1：300mm×450mm、 B2：450mm×450mm、B3：450mm×600mm，three levels）of wet curtain needed underdifferent temperature.The CK is the index of Vegetable seed-nurturing containerunder nature circumstance in which hot pepper seedling were also nurtured. Thisexperience intended to provide proper environmental index hot pepper seed-nurturingneeded in Vegetable seed-nurturing container and sort out the best soilless cultivationsolutions. The result:Setting three Fluorescent lamps (36W) on the top of each layer (except firstlayer) can meet the light need of hot pepper seedlings, the growing index of hotpepper seedlings were better than that of treatment A1and CK.The area of wet curtain can regulate the temperature in the Vegetableseed-nurturing container. The area450mm×450mm was the best in regulating thetemperature for the growing of hot pepper seedlings. The growing index of hot pepper was better than that of treatment B1and B3.The form and physiology index of hot pepper seedling(30days) showed that:treatment T2seedling substrate (mushroom residue: peat: vermiculite=50%：25%：25%) was best to nurture hot pepper seedling.Two supplementary lamp set in one full light vegetable nursery box can increasethe light intensity to3950lux, the area of wetted pad was450mm, fully meeting theneeds of the hot pepper seedling growth.
