Embodiment 1

[0042] Embodiment 1 strengthens the compost decomposing material preparation

[0043] 125 parts of pig manure, 30 parts of corn stalks, 20 parts of wheat stalks and 25 parts of soybean meal were preliminarily mixed by weight ratio with a forklift and stacked into strips with a width of 3.5 m and a height of 1.5 m, and then the water content was adjusted to 55%. Four treatments are carried out: conventional composting, improved composting①②and enhanced composting:

[0044] Conventional composting is composting by turning pig manure, straw, and soybean meal twice with a turning machine.

[0045] Improved composting ① Sprinkle 0.5 parts of sulfur evenly on the surface of the pile, turn it over twice with a turning machine to fully mix pig manure, straw, soybean meal, sulfur and superphosphate for composting.

[0046] Improved composting ② is to evenly sprinkle 2 parts of superphosphate on the surface of the pile, and use a turning machine to turn it twice to fully mix pig manure...

Embodiment 2

[0052] Embodiment 2 preparation of special organic fertilizer

[0053] Get the strengthened compost decomposed material of embodiment 1. Mix 82 parts of enhanced compost decomposed materials with 8 parts of amino acid liquid, 5 parts of potassium fulvic acid, 4 parts of montmorillonite, 1 part of gypsum powder, and 0.4 parts of magnesium carbonate in a mixer according to the weight ratio, and then crush them through a 1mm sieve through a pulverizer Disc granulation. Sieve the granulated fertilizer to get 2-4mm granules, which is the special organic fertilizer.

[0054] After testing, the special organic fertilizer obtained in this embodiment has a pH of 6.46, a water content of 29.1%, an organic matter content (in terms of organic fertilizer dry basis) of 48.2%, an amino acid content (in terms of organic fertilizer dry basis) of 1.68%, and a humic acid content of (Based on dry basis of organic fertilizer) 26.3%. See Table 2 and Table 3 for the nutrient properties and medium...

Embodiment 3

[0060] The nutrient release characteristic of embodiment 3 special-purpose organic fertilizers in soil

[0061] See Table 4 for the organic state and available nitrogen, phosphorus and potassium nutrient contents of the commercially available pig manure straw organic fertilizer, the enhanced composting material in Example 1, and the special organic fertilizer in Example 2.

[0062] Table 4 special organic fertilizer available and organic nutrient properties

[0063]

[0064]

[0065] In the onion and garlic planting base in Shouxian Town, Fengxian County, the commercially available pig manure straw organic fertilizer, enhanced compost and decomposed material and special organic fertilizer were added to 2.5 square meters of soil (no crops were planted), all applied at a rate of 500kg / mu. Each treatment plot is surrounded by cement partitions, and the cement is buried to 40cm underground to cut off the flow of nutrients inside and outside the plot. On September 30, 2019, ...

Abstract

The invention discloses a special organic fertilizer for sandy soil and a preparation method and application thereof. The organic fertilizer is prepared from the following components: 80 to 85 parts of reinforced compost matured material, 5 to 9 parts of amino acid liquid, 3 to 6 parts of potassium fulvate, 3 to 5 parts of montmorillonite, 0.5 to 1 part of gypsum powder and 0.2 to 0.4 part of magnesium carbonate. The reinforced compost matured material is obtained by the following method: mixing 110-130 parts of pig manure, 50-65 parts of straw, 20-30 parts of soybean meal, 0.3-0.6 part of sulfur and 1.5-2.5 parts of calcium superphosphate, adjusting the water content to 55-60%, and performing composting fermentation; according to the special organic fertilizer, the content of organic nitrogen and potassium nutrients is increased by 5% or above, the release rule of the organic nitrogen and potassium nutrients coincides with the fertilizer requirement rule of scallions and garlics, the effective sulfur content is increased by 0.4% or above, and the special quality of the scallions and garlics is improved; the organic fertilizer effectively reduces loss of nitrogen and potassium nutrients in sandy soil on the premise of stable yield or yield increase of garlic and onions, effectively reduces application of more than 40% of chemical fertilizer, and is easy to popularize and apply in sandy soil.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a special organic fertilizer for sandy soil and its preparation method and application. Background technique [0002] Onion and garlic vegetables (such as garlic and onion) are important open-field vegetables in my country, and are widely planted in Hebei, Henan, Jiangsu, Shandong and other places. This kind of vegetable crops is resistant to storage and transportation, has a long supply period, and has a wide variety of processed products. It plays an important role in ensuring a balanced annual supply of vegetables, and plays an important role in increasing agricultural efficiency in production areas, increasing farmers' income, and rural economic and social development. [0003] Sandy soil is better for onion and garlic vegetables, because sandy soil is loose and breathable, and the temperature rises quickly, which is conducive to the growth and development of bulbs. Its ma...
