Abstract

The invention discloses a method for preparing a machine-transplanted rice seedling raising substrate by taking a rice straw fermentation product as a raw material. According to the preparation method, rice straw wastes are used as a raw material and are fermented by using a variety of beneficial microorganisms for 40-60 days to obtain a microbial organic fertilizer which is used for preparing the rice seedling raising substrate together with perlite, vermiculite, peat, a water retention agent and biocontrol bacteria in proportion, and the substrate is small in volume weight, is convenient to carry, is good in water holding capacity to reduce the irrigation frequency and reduce the water consumption, and has rich nutrient substances to avoid additional fertilizer in the whole seedling raising period; rice seedlings come out neatly and are high in root system activity coefficient; and the substrate is low in cost and strong in compatibility with a machine-transplanting technology, and can not only reduce the usage amount of paddy field soil, but also avoid the risk of causing pollution to the environment due to improper treatment of straws.

Description

technical field

[0001] The invention belongs to the fields of rice seedling raising and utilization of agricultural waste, and in particular relates to a machine-transplanted rice seedling raising substrate using fermented rice straw as a raw material and a preparation method thereof. Background technique

[0002] With the development of society and economy, the transfer of rural labor force and the aging of rural labor force, there is an urgent need for rice mechanized production technology based on machine transplanting. Machine transplanting has the advantages of reducing labor intensity, saving seedling beds, saving labor, high and stable production, cost saving and efficiency enhancement, etc. It is useful for developing large-scale rice farming, promoting labor transfer, improving labor productivity and land productivity, stably developing food production, and promoting my country's modern agriculture. development matters. Cultivating a substrate suitable for the growt...
