Embodiment 1

[0028] 800kg of corn stalk powder, 8kg of Tianyuan mother dew fermented bacterial liquid (produced by Qingdao Tianyuan Co., Ltd.), 13.4kg of bean cake, and 2.7kg of urea. First, dissolve urea in water, then add straw powder and mix thoroughly, and pile up the treated straw powder into a trapezoid with a height of 1.2 meters, a bottom width of 3 to 5 meters, and a length of more than 5 meters. Then, dilute the fermented bacteria liquid with groundwater (groundwater for fermentation is best, if tap water needs to be left for 24 hours before use) at a ratio of 1:5, stir well, mix with bean cake and some straw powder evenly, and sprinkle it on the trapezoidal straw powder pile top. Turn the pile 3 to 4 times from one side, and adjust the water content to about 60%. Then, cover it with plastic sheeting and straw curtains, and compact it around. Whenever the temperature in the pile rises to 60-80°C, turn the pile once. During this period, the humidity in the heap is kept at about...

Embodiment 2

[0032] 800kg of rice husk straw powder, 9.6kg of Tianyuan mother dew fermented bacterial liquid (produced by Qingdao Tianyuan Co., Ltd.), 16kg of bean cake, and 4kg of urea. Others are with embodiment 1. The fermentation period is 68 days.

[0033] Mix 100Kg of the above-mentioned straw fertilizer and 70Kg of sandy loam to raise tobacco seedlings. The root system of the tobacco seedlings is developed, with more soil, the length of the leaves of the tobacco seedlings is 9.9cm, and the width of the leaves is 5.4cm. Yield 142kg.

Embodiment 3

[0035] 800kg of soybean straw powder, 6.4kg of Tianyuan mother dew fermented bacterial liquid (produced by Qingdao Tianyuan Co., Ltd.), 10kg of bean cake, and 2.4kg of urea. Others are with embodiment 1. The fermentation period is 52 days.

[0036] The straw fertilizer 100kg made above is mixed with sandy loam 120kg to carry out tobacco seedling cultivation. The root system of tobacco seedlings is well developed. The length of tobacco seedling leaves is 9.2cm, and the width of leaves is 4.9cm.

Abstract

The invention relates to a nutrient soil for tobacco cultivation and a manufacturing method thereof. The composition of the nutrient soil is measured in parts by mass. Straw fertilizer 100, sandy loam 50-120. The production method is as follows: production of straw fertilizer: in parts by mass: straw powder 100, fermented bacteria liquid 0.8-1.2, bean cake 1.5-2.0, urea 0.3-0.5. Mix and stir evenly, the water content of the fermented product is 60% to 70%, and stack it. When the temperature in the stack reaches 60 ~ 65°C, turn it over. . The nutrient soil for raising tobacco seedlings of the invention solves the problem of nutrient soil for growing tobacco seedlings in mother beds and false plantings, replaces humus soil, and achieves the purpose of protecting the ecological environment. Compared with peat soil, the cost of raising seedlings is low. There is no need for soil disinfection, which plays a great role in the development of green agriculture and the reduction of smoking hazards. Crop straw and sandy loam resources are abundant, and the straw fertilizer fermentation method is easy to operate, easy to implement, and low in cost.

Description

technical field [0001] The invention relates to a tobacco cultivation nutrient soil, in particular to a fermented straw compound nutrient soil and a manufacturing method thereof. Background technique [0002] Tobacco seedlings use a relatively large amount of humus soil. At present, the production mainly uses humus soil (mountain skin soil) from broad-leaved forests. About 0.086m2 of mountain soil is needed to supply one mu of flue-cured tobacco seedlings 3 . Generally, the thickness of the mountain skin is about 2.5cm, and it takes 20 to 30 years to form. The water absorption capacity of mountain soil can reach 2 to 4 times of its own weight, and its function can reduce surface runoff. The consequence of clogging the mountain's skin and soil is that the water storage capacity of the mountain body is reduced. If things go on like this, the surface runoff will increase, which will inevitably lead to soil erosion and ecological imbalance. [0003] At present, peat soil is ...
