Problems solved by technology

According to estimates, the annual output of crop straw in Hubei Province alone is 28.24 million tons, of which rapeseed straw accounts for 17.2%. Rapeseed straw contains 0.82% nitrogen (N), 0.32% phosphorus (P), and potassium (K 2 O) 2.24%. However, due to the concentration of rapeseed harvesting seasons and the lack of ways to comprehensively utilize straw, most of them are burned in the open air or degraded naturally, which can easily cause air pollution and waste of resources

Embodiment 1

[0019] The volume ratio of rape straw, pastoral soil and vermiculite in the seedling raising matrix composition of this example is 2:2:6, and every 10m 3 Inorganic fertilizers need to be added to the substrate, and the weights in terms of pure nutrients are: nitrogen 180g, phosphorus pentoxide 60g, potassium oxide 120g. The nutrients in the inorganic fertilizer are provided by the following substances: nitrogen: urea; phosphorus pentoxide: calcium magnesium phosphate fertilizer; potassium oxide: potassium chloride.

[0020] Inorganic fertilizers converted into commercial fertilizers and the physical quantity of main raw materials are selected from the following substances (to produce 10m 3 In terms of seedling-raising substrates, the natural loss of the product during processing is not calculated. If natural loss occurs, the actual amount of each formula can be increased synchronously in proportion according to the conventional methods in this field, the same below):

Abstract

The invention belongs to the technical field agricultural farming and relates to a seedling cultivation matrix composition with rape stalks as main raw materials and application of the seedling cultivation matrix composition. The volume ratio of the rape stalks, rural soil and vermiculite in a seedling cultivation matrix is 2-4:1-3:4-6. According to measurement of pure nutrients, inorganic fertilizers of the seedling cultivation matrix composition of 10m <3> comprise, by weight, 110-180g of nitrogen, 30-60g of phosphorus pentoxide and 60-120g of potassium oxide. The seedling cultivation matrix composition is wide in source of the raw materials, low in cost, easy to process, high in emergence rate, free of disease and pest injury, complete in nutrient type and reasonable in matching and enables local materials to be use. Compared with the prior art, rice seedlings, rape seedlings and cotton seedlings are cultivated by the composition and come out evenly, the average emergence rate of the rice seedlings, the average emergence rate of the rape seedlings and the average emergence rate of the cotton seedlings are improved by 5%, 7% and 6% respectively and averagely, the quality is good, seedling recovering time is short after the seedlings are transplanted, and the survival rate of the rice seedlings, the survival rate of the rape seedlings and the survival rate of the cotton seedlings are improved by 7%, 9% and 4% respectively and averagely.

Description

technical field [0001] The invention belongs to the technical field of planting industry, and in particular relates to a seedling-raising substrate composition with rape stalks as the main raw material and its application. Background technique [0002] Substrate cultivation is an important form of soilless cultivation, and now most countries use substrate cultivation for soilless cultivation of fruits and vegetables. Since the mid-1980s, my country has begun to introduce vegetable seedling raising technology characterized by light substrates and plug seedlings, and has been favored by vegetable and flower producers. In recent years, plug seedlings have begun to be applied to the seedlings of field crops. The main advantages of plug substrate seedling cultivation are labor-saving, labor-saving, low cost, high survival rate and high efficiency, and no pests and diseases. The mechanization, scale and sustainable and efficient development of agricultural production are of grea...
