Abstract

The invention belongs to the technical field of rice culture substrates, and specifically relates to a special substrate using astragalus sinicus as a raw material for raising machine-transplanted rice seedlings and a production method of the special substrate. The special substrate is characterized by containing the following raw materials in percentage by weight: 10-30% of astragalus sinicus, 20-40% of distillers' grains, 20-40% of rice husk, 3-8% of a water retaining agent, 2-5% of a bonding agent and 0.2-0.5% of a root growth promoting agent. The substrate for raising the rice seedlings is an environment-friendly, light-duty and soil-less substrate for raising machine-transplanted rice seedlings, and the method is reasonable in design and easy to operate. The substrate is low in raw material cost, simple in operating technology, light in weight, and high in compatibility with a machine transplanting technology, thereby being a preferred substrate for development of green organic agriculture.

Description

technical field [0001] The invention belongs to the technical field of rice culture substrates, and in particular relates to a special substrate for machine-transplanted rice seedlings with milk vetch as a raw material and a production method thereof. Background technique [0002] In recent years, with the country's emphasis on agricultural production and food security, support policies for food production have increased, and machine-transplanted rice has developed rapidly. However, at present, machine-transplanted rice adopts soil seedling cultivation and transplanting with soil, and the required nutrient soil is all taken from farmland or forest land cultivation layer, and a large amount of soil is taken every year to seriously damage the soil cultivation layer. According to calculations, every 1500 mu of machine-transplanted rice seedlings will destroy 1 mu of farmland or forest land cultivation layer soil. At the same time, it takes a lot of labor to make, transport, an...
