Abstract

The invention discloses an ecological fertilizer for vegetable cultivation and a preparation method thereof. The raw material composition of the ecological fertilizer comprises the following components in parts by weight: 40-50 parts of plant stems and leaves, 55-65 parts of excrements of livestock, 10-15 parts of rapeseed dregs, 5-10 parts of rice husk and 10-15 parts of 10 percent of urea solution. The method comprises the following preparation steps: a) cutting the plant stems and leaves into sections, wherein the length of each section is not more than 5cm; b) mixing the components according to the ratio, mixing and uniformly spraying the proportioned urea solution into the mixture; and c) burying the obtained mixture in the step b) in a dug hole, covering the surface through straws, and obtaining the finished ecological fertilizer within 90 days. Because the main raw materials are useless crops stems and leaves and excrements of livestock, the fertilizer is low in production cost, the resources are not wasted, the fertilizer is environment-friendly, even if excessive fertilizer is used, the vegetables are not damaged, and the practice proves that after the vegetables are plants by using the fertilizer, various growth indexes of the vegetables can achieve the effects of the common fertilizer.

Description

Be used for ecological fertilizer of growing vegetables and preparation method thereof

Technical field

The present invention relates to agricultural technology field, particularly a kind of ecological fertilizer and preparation method thereof.

Background technology

At present, the fertilizer that the farm crop such as vegetables are used adopts chemical industry fertilizer more, but chemical fertilizer exists following youngster to put deficiency: 1) may weaken vegetables throughput.The excessive result that vegetables are worked the mischief of applying fertilizer mainly contains two: one is easy lodging, and lodging is in case appearance just must cause the underproduction; Another is that disease and pest easily occurs, and nitrogen application is too much, and vegetable disease-resistant worm ability is weakened, and subjects to the disease worm and infects, and then increases the pesticide dosage that destroys plant diseases and insect pests, and has directly threatened the security of food; 2) aggravation environmental pollution.When the fertilizer amount of too much using surpasses the hold facility of soil, in the water around will flowing into, form widespread pollution from the overuse of fertilizers and pesticides in rural area, eutrophication, cause algae to grow, then destroy water surrounding.According to statistics, China is annual because unreasonable fertilising causes the nitrogen loss of more than 1,000 ten thousand tons outside the farmland, approximately 30,000,000,000 yuan of direct economic losses.Excessive fertilizer also can infiltrate 20 meters with in interior shallow ground water, makes Nitrate content in ground water increase.3) waste a large amount of narrow resources.If the chemical fertilizer that slatterns can be saved, will alleviate the energy scarcity situation of China.Only in 2004, China's chemical fertilizers production consumed about 100,000,000 tons of standard coals, surpassed national energy and consumed 5% of proportion.In addition, the annual higher-grade Rock Phosphate (72Min BPL) that consumes of China's chemical fertilizers production has surpassed 100,000,000 tons, and Rock Phosphate (72Min BPL) has been listed the row of Ministry of Land and Resources's narrow resources after 2010 in; Chemical fertilizers production has also consumed the sulphur resource of China 72%.

For above-mentioned deficiency, need to explore a kind of ecological fertilizer that can utilize renewable resources to produce, when making it be used for growing vegetables, excessively can not produce harm even apply fertilizer yet, and environmental protection and energy saving.

Summary of the invention

In view of this, the invention provides a kind of ecological fertilizer for growing vegetables and preparation method thereof, this ecological fertilizer adopts reproducible farm crop as main raw material, by special preparation technology's production, effectively solve existing fertilizer and excessive harm easily occurs, environmental hazard is reached greatly the large technical problem of production energy consumption.

The present invention solves the problems of the technologies described above by following technique means:

At first the present invention discloses a kind of ecological fertilizer composition for growing vegetables, comprises by weight following component:

Plant stem-leaf 40-50;

Feces of livestock and poultry 55-65;

Rapeseed meal 10-15;

Husk 5-10;

Concentration is 10% urea soln 10-15.

Further, described composition comprises following component by weight:

Plant stem-leaf 45;

Feces of livestock and poultry 60;

Rapeseed meal 12;

Husk 8;

Concentration is 10% urea soln 12.

Further, described plant stem-leaf is potato haulm or sweet potato stem leaf.

In addition, the invention also discloses a kind of method of using described composition to prepare ecological fertilizer, the method comprises the following steps:

A) plant stem-leaf is cut into joint, every joint length is not more than 5cm;

B) get axis leaf segment, feces of livestock and poultry, rapeseed meal and husk by described proportioning and mix, the urea soln while mixing with described proportioning evenly is spilled into mixture;

C) with step b) mixture of gained buries after digging pit, and the surface uses stalk to cover, and buries after 90 days to get the finished product ecological fertilizer.

Beneficial effect of the present invention: ecological fertilizer for growing vegetables of the present invention and preparation method thereof, its feedstock composition comprises following component by weight: plant stem-leaf 40-50; Feces of livestock and poultry 55-65; Rapeseed meal 10-15; Husk 5-10; Concentration is 10% urea soln 10-15.Its preparation process is: a) plant stem-leaf is cut into joint, every joint length is not more than 5cm; B) get axis leaf segment, feces of livestock and poultry, rapeseed meal and husk by described proportioning and mix, the urea soln while mixing with described proportioning evenly is spilled into mixture; C) with step b) mixture of gained buries after digging pit, the surface uses stalk to cover, bury after 90 days to get the finished product ecological fertilizer, because main raw material adopts useless farm crop cauline leaf etc. and feces of livestock and poultry, the fertiliser production cost is low, consumes resources not, and fertilizer is environmentally friendly, even and excessive fertilization can not work the mischief to vegetables yet, be proven, after using this ecological fertilizer planting vegetable, every growth indexes of vegetables all can reach the effect of using common chemical fertilizer.
