辣椒育苗处于冬春季节,气温低,光照弱,蒸发量小,如遇连续阴雨雪天,棚内湿度大,移苗床水份不易散发,易发生病害,影响秧苗生长发育。试验对辣椒苗期松土和未松土比较,苗期松土能提高苗床土温,降低苗床湿度,增强土壤通透性、促进秧苗根系发育,为培育壮苗创造良好条件。一、材料与方法 1.试验在葛塘镇新桥村科技队进行。1988年11月28日,对辣椒移苗活棵后(11月5日移苗)在行间进行松土,深度为6厘米左右,面积0.15亩,同时设0.15亩未松土作对照,在同一大棚内,未设重复。
Pepper nursery is in winter and spring, the temperature is low, the light is weak, the evaporation is small, in case of continuous rainy and rainy days, shed humidity, seedling bed moisture is not easy to disseminate, prone to disease, affecting seedling growth and development. Compared with the test, the soil looseness at the seedling stage can increase soil temperature, reduce the humidity of the seedbed, enhance the soil permeability, promote the root development of the seedling, and create good conditions for cultivating the seedling. First, materials and methods 1 test in Ge Town, Newbridge Village Science and Technology team. November 28, 1988, after the pepper live seedlings (November 5 transplant seedlings) between the line of loose soil, a depth of about 6 centimeters, an area of 0.15 acres, while set aside 0.15 acres of unsuspended soil for control, in the The same greenhouse, there is no duplication.
