Embodiment 1

[0037] (1) According to the volume ratio of papermaking sludge: mushroom slag: sawdust = 3:6:1, a total of 100m is weighed 3 Crush the raw material to 30mm, and slowly pour water for 2 to 3 days to make the moisture content reach 60% (the judgment standard is to hold a handful of substrate firmly, and it is better if water overflows between fingers and does not flow out). Add 50kg of urea, mix evenly, pile into a pile with a width of 2.0m and a height of 1.5m, and ferment;

[0038] (2) Turn the pile for the first time after the fermentation temperature of the pile rises to 60°C and last for 48 hours; when the temperature of the pile rises to 55°C again, turn the pile for the second time so that the temperature of the pile drops below 40°C, and then continue Aging on the ground without hard bottom for 20 days to complete the compost fermentation;

[0039] (3) Spread the fermented compost in the air to keep the moisture content below 12%, and then mix it with perlite and peat s...

Embodiment 2

[0042] (1) According to the volume ratio of papermaking sludge: mushroom slag: sawdust = 2:7:1, a total of 100m is weighed 3 Crush the raw material to 50mm, slowly pour water for 2 days to make the moisture content reach 50% (judgment standard is to hold a handful of substrate firmly, and it is advisable that water overflows between fingers and does not flow out). Add 30kg of urea, mix evenly, pile into a pile with a width of 3.0m and a height of 2.0m, and ferment;

[0043] (2) After the fermentation temperature of the heap rises to 55°C and lasts for 72 hours, the first turning is carried out; when the temperature of the heap rises to 50°C again, the second turning is made to reduce the temperature of the heap to below 40°C, and then continue Aging on the ground without hard bottom for 15 days to complete the compost fermentation;

[0044](3) Spread the fermented compost in the air to make the moisture content lower than 12%, and then mix it with perlite and peat soil at a v...

Abstract

The invention discloses a method for rapidly fermenting and producing a seedling-raising substrate by using papermaking sludge. The seedling-raising substrate is produced by using the papermaking sludge, which greatly reduces the amount of peat soil and is a sustainable, environmentally friendly and inexpensive cultivation substrate. The production method is simple and controllable, does not need additional fermentation agent, has low investment in production facilities, is relatively easy to manage, is convenient for factory production, has low comprehensive economic cost, and is easy to popularize the complete set of technologies. Utilizing the substrate of the invention to cultivate eucalyptus has high seedling survival rate, fast initial growth speed, well-developed seedling root system, strong resistance and good seedling raising effect.

Description

technical field [0001] The invention belongs to the technical field of cultivation substrate production, in particular to a method for rapidly fermenting papermaking sludge to produce seedling cultivation substrates. Background technique [0002] The soilless cultivation substrate is a growth medium that can provide plants with a stable and coordinated water, air, and fertilizer structure. In addition to supporting and fixing the plants, it is more important to act as a nutrient and water carrier, so that the nutrients and water from the nutrient solution can be obtained. Transit, the plant root system selects and absorbs from it as needed. At present, 90% of the soilless cultivation in the world is substrate cultivation. Substrate is the foundation and core of soilless cultivation, so the selection and formula research of substrate is the key to the success of cultivation. Due to the defects in physical and chemical properties of a single substrate, it is difficult to mee...
