Melon seedling raising substrate and preparation method thereof

Abstract

The invention discloses a melon seedling raising substrate and a preparation method thereof. The melon seedling raising substrate is prepared from, by volume, 60% of turf, 20% of vermiculite and 20% of perlite; the range of the total amount of added nitrogen, phosphorus and potassium nutrient is 3 g / kg, 4 g / kg, 5 g / kg, 6 g / kg, 7 g / kg and 8 g / kg. According to the growing day number of melons, scions for grafting of the melons less than 10 days adopt 3 g / kg of the nitrogen, phosphorus and potassium nutrient (the ratio of nitrogen to phosphorus to potassium is 4:3:3) or 4 g / kg of the nitrogen, phosphorus and potassium nutrient (the ratio of nitrogen to phosphorus to potassium is 4:2:4), the small-seedling-age melons more than 10 days and less than 15 days adopt 5 g / kg of the nitrogen, phosphorus and potassium nutrient (the ratio of nitrogen to phosphorus to potassium is 3:3:4), and the middle-and-big-seedling-age melons more than 15-25 days adopt 6 g / kg of the nitrogen, phosphorus and potassium nutrient (the ratio of nitrogen to phosphorus to potassium is 2:2:6) or 7 g / kg of the nitrogen, phosphorus and potassium nutrient (the ratio of nitrogen to phosphorus to potassium is 2:3:5) or8 g / kg of the nitrogen, phosphorus and potassium nutrient (the ratio of nitrogen to phosphorus to potassium is 2:3:5.5) in sequence, and in each cubic meter of substrate materials, the above proportion of monopotassium phosphate, potassium sulphate and urea are added. The melon seedling raising substrate and the preparation method thereof have the advantage that according to the characteristics ofnutrient requirements of melon seedling raising, a nutrition medium capable of meeting the growth requirements of melon seedlings (the seedling age is within three leaves and one core is prepared tomeet the growth needs of the melons in the seedling stage.

Description

technical field [0001] The invention relates to the technical field of seedling-raising substrates, and more specifically relates to a melon seedling-raising substrate and a preparation method thereof. Background technique [0002] Along with the scale, standardization and specialization of vegetable production in my country, the industrialized substrate plug seedlings have developed rapidly, and the demand for seedling substrates has continued to increase. At present, the seedling substrate is mainly composed of peat, vermiculite, perlite, etc. mixed in a certain proportion. A good seedling substrate can provide stable and coordinated water, fertilizer, air, heat and other conditions for the growth of plant seedlings, and has the functions of fixing and supporting plants, supplying water and nutrients, loosening ventilation, etc.; nitrogen, phosphorus, and potassium are the main nutrients for seedling growth and development, and Different types of vegetable seedlings and d...
