(3) stacking the mixed soil for 3-5 days for paving and sprinkling water;

(4) planting in a wet state, and adding 2.5 kg-20 kg of soil conditioner into each pit of a tree pit at the position of the transplanted tree;

the soil conditioner comprises crushed mushroom waste, crushed charcoal soil, pond sludge and plant ash, and the soil conditioner comprises the following components in percentage by weight: 30-50% of crushed materials of the fungus stick waste, 20-35% of biochar soil, 10-25% of pond sludge and 5-15% of plant ash.

Preferably, the method for improving sandy soil further comprises:

(5) sprinkling water after planting to keep the ground in a wet state;

(6) and in the later period, the granulated product is used for topdressing, and 50 kg-300 kg of topdressing is carried out per mu each time according to the growth condition of plants.

Preferably, the gravel soil improvement method comprises the steps of circularly and hierarchically spreading crushed mushroom rod waste, crushed biochar soil and pond sludge in sequence, uniformly ploughing, moistening, uniformly stirring, stacking and fermenting, adding plant ash after stacking and fermenting, and watering and moistening in the uniform ploughing process.

Preferably, in the method for improving sandy soil, the soil conditioner further comprises the following steps after the plant ash is added: sequentially carrying out high-temperature sterilization, disinfection, drying treatment and packaging to obtain the finished product.

Preferably, in the method for improving sandy soil, the soil conditioner further comprises the following steps after the plant ash is added: sequentially adding 20-40% of sludge and flocculating agent of a domestic sewage treatment plant, sterilizing at high temperature, drying and granulating.

Compared with the prior art, the scheme has the following advantages and technical effects:

the soil improvement method can effectively improve the fertility of the soil, can correspondingly reduce the use of chemical fertilizers, has relatively light modifier, effectively avoids the harm of dust caused by improvement spreading due to the addition of pond sludge, and is convenient to use; the preparation process is simple, the requirement on production conditions is low, the fertilizer can be prepared on the improved engineering site, and the production cost is lower than that of the common fertilizer.

Detailed Description

The present invention is explained and illustrated in detail below with reference to specific embodiments so that those skilled in the art can better understand the concept of the present invention and can carry out the present invention.

Example 1 soil conditioner preparation

The sandy gravel soil modifier comprises crushed materials of mushroom stick wastes, crushed biochar soil, pond sludge and plant ash.

The preparation method comprises the following steps:

step 1, field preparation: selecting a material stacking fermentation field, and conveying bagged mushroom stick waste, biochar soil and plant ash to a stock dump for stacking separately, wherein the plant ash is covered to keep a dry state;

step 2, material treatment: smashing or crushing bagged mushroom stick waste to form mushroom stick granules, sieving biochar soil by a 2mm sieve, crushing the biochar soil by a crusher to form biochar soil granules, and carrying out artificial carbon head removing treatment on plant ash.

Step 3, layering and paving materials: spreading water with the thickness of 10-25 cm on a fermentation field to spray wet crushed mushroom stick waste, spreading 3-10 cm of crushed biochar soil in a forest on the crushed mushroom stick waste, spraying pond sludge filled by a pump of a pump truck on the biochar soil by using a pump, wherein the thickness of the deposited sludge is 2-6 cm, and spreading 1-2 layers again according to the three layers;

step 4, composting, turning over and stirring uniformly: after spreading, uniformly ploughing by using a ploughing machine after 12 hours, locally watering in the ploughing process to ensure that the aggregate is wet (the good condition is that no clear water appears due to hand grabbing and extrusion), and uniformly stirring by using a stirrer after moistening;

step 5, aggregate stacking: using a bulldozer to push the aggregates with even ploughing, wherein the total stacking thickness is 0.6-2 m, the stacking width L is 2-3 m, the clear spacing H on the stacking ground is more than 0.8m, and the stacking slope is put to obtain 1: 0.5-1: 2;

step 6, aggregate fermentation: carrying out microbial fermentation on the stack, wherein the temperature of the surface layer of the stack is ensured to be above 5 ℃, turning the inside and the outside of the stack aggregate, stirring for 3-5 days, turning and stirring for 3-7 times in the fermentation period, and basically completing the fermentation after 15 days of fermentation (the fermentation time can be properly prolonged according to the field conditions so as to ensure the optimal fermentation);

step 7, adding plant ash: after fermentation, performing pH detection, adding 5-15% plant ash into the fermented aggregate, mixing, and performing pH fine adjustment to meet the pH of vegetation growth, thereby preparing an available modifying agent;

step 8, modifier product preparation: if the product is conveyed to a place other than the producing area, high-temperature sterilization and disinfection are required, drying treatment is carried out, and the product is packaged to be prepared into a finished fertilizer for application; if the composition is used in the production place, the composition can be used after being prepared at the present place without sterilization, disinfection and drying.
