我县蘑菇种植面积至1989年已达100多万m~2,其产量的高低在很大程度上影响着我县的经济收入。有着与秋菇收获期同样长的春菇,由于种种原因,产量一直徘徊在8.1～12.15kg/m~2,仅占总产量的15～20%。为了提高春菇产量,我们自1985年起对影响春菇产量的原因,在查阅了有关资料后还进行了一些试验与调查,现将结果报告于后。(一)培养料的数量和质量蘑菇是一种腐生菌,不能进行光合作用,完全依靠培养料中的营养物质进行生长发育。因此在培养料中必须具备充足的供蘑菇生长发育的各种营养物质。在春菇生产期间,经过秋季旺产和越冬,料内养分已大为减少,因此要使春菇期间料内养分充足,必须投料充足,长效肥含量高。我们通过下列试验和调查也证实了这一点。1.投料量试验:培养料配方为稻草73.3%、麦草20%、尿素1.7%、磷肥和石膏各2.5%。设四个不同投料量处理,3次重复,小区面积0.83m~2,品种为浙农一号。产量结果如下表:
The area of mushroom cultivation in our county reached more than 1 million m ~ 2 in 1989, and the output of the county affected the income of our county to a great extent. With the same harvest of autumn mushrooms spring mushrooms, for various reasons, production has been hovering at 8.1 ~ 12.15kg / m ~ 2, accounting for only 15 to 20% of total output. In order to improve the yield of spring mushrooms, we have been influencing the production of spring mushrooms since 1985, and have conducted some tests and surveys after consulting the relevant materials. The results are reported later. (A) the amount and quality of training materials Mushroom is a saprophytic, can not carry out photosynthesis, rely entirely on nutrients in the culture material for growth and development. Therefore, in the training material must have adequate for mushroom growth and development of various nutrients. During the production of spring mushrooms, after the strong harvest in autumn and wintering, the nutrient content in the material has been greatly reduced. Therefore, enough nutrients should be supplied during the spring mushroom season, and the content of long-acting fertilizer should be high. We have also confirmed this through the following tests and surveys. 1. Feeding volume test: The training material formula is straw 73.3%, wheat straw 20%, urea 1.7%, phosphate and gypsum each 2.5%. Set four different feeding amount of processing, three repetitions, the plot area of 0.83m ~ 2, the type of Zhejiang agriculture on the 1st. Yield results in the following table:
