大棚生产在我市已七年之久,近年来栽培面积迅速扩大,产量逐步提高,花色品种不断增多。但是,如何结合本地区的气候特点,提高大棚利用率,研究肥、水、温、光、气等因素与丰产的关系及其理论依据,仍是目前需要探讨的问题。一、根据气候特点,抓好三茬生产。我省地处中原,春季多风少雨,气温回升快;夏季炎热多雨,气温高,昼夜温差小;秋季气候温和,但温度下降快;冬季虽干冷多风,但气温并不太低。而且,
Greenhouses production in our city has been seven years, in recent years the rapid expansion of cultivation area, production gradually increased, the growing variety of colors. However, how to combine the characteristics of the climate in the region, improve the utilization rate of greenhouses, and study the relationship between the factors of fertilization, water, temperature, light and gas and high yield and their theoretical basis are still the issues that need to be discussed at present. First, according to the characteristics of the climate, do a good job three crop production. The province is located in the Central Plains, the spring breeze and a little rain, the temperature picked up quickly; the summer is hot and rainy, high temperatures, small temperature difference between day and night; the autumn climate is mild, but the temperature dropped rapidly; winter though dry and windy, but the temperature is not too low. and,
