Description
Technical Field
The invention relates to the technical field of rice planting, in particular to an organic rice planting method using biogas slurry for fertilization in a fallow period.
Background
In recent years, the safety problem of agricultural products frequently occurs, and green health food becomes the most concerned focus of people in modern diet. Organic agricultural products are sought after due to the characteristics of no pollution, health, safety and high quality, and even if the market price is several times or even more than ten times of that of common products, the organic agricultural products still meet the demand. In the production process of organic products, organisms and products thereof obtained by genetic engineering are not adopted, and chemically synthesized pesticides, chemical fertilizers, growth regulators and other substances are not used, so that the crop diseases and insect pests are serious, the yield is low, and the large-scale popularization of organic agriculture in China is limited.
The rice is one of three main grain crops in China, the planting area is wide, the yield is high, but the market value of the common rice is low, so that the return rate of investment in the traditional single rice planting is extremely low, and the enthusiasm of farmers cannot be mobilized. In order to obtain higher economic benefit, planting modes such as rice and fishing planting, rice and duck planting and the like are also successively created and widely popularized. However, in any mode, once the organic management mode is adopted, the yield of the rice is low, only 1/3-2/3 of the original yield is obtained, and the yield reaches 6t/hm even under the condition of good management and rich year2Has been of high yield. The limitation of the yield of the organic rice causes the income of growers to increase slowly, which cannot reach the psychological expectation.
Organic rice planting can only supplement soil fertility by returning straws to fields and applying organic fertilizers, but the total nutrient content of the organic fertilizers is very low, is only about 5 percent, and is far from being compared with chemical fertilizers. In addition, the nutrients in the organic fertilizer are mainly organic, can be released to be utilized by rice through the action of microorganisms, and have slow effect, so that the quick and large demand of the rice on the nutrients in the nutrition period and the reproduction period cannot be met. Although the defect of insufficient nutrients can be made up by increasing the application amount of the organic fertilizer, the current commercial organic fertilizer is expensive, so that the input cost is greatly increased, the output and the input are not proportional, and finally, the pure income is reduced. Meanwhile, chemical pesticides cannot be used in the organic rice planting period, so that the incidence rate of plant diseases and insect pests is greatly increased, the damage is serious, and the yield of the rice is greatly reduced.
Biogas fermentation is a method for retaining most nutrients in an agricultural waste treatment method, and the total nutrients in biogas slurry account for more than 85%. The nutrients in the biogas slurry are mainly quick-acting nutrients, can be quickly absorbed and utilized by plants, and are a slow and compatible liquid organic fertilizer. The existing research shows that the average nitrogen of about 3/4 is biological effective nitrogen, the content of phosphorus in the biological effective state accounts for about 85% of the total phosphorus content, and the content of potassium in the biological effective state accounts for 81% of the total potassium content. Besides, the biogas slurry also contains rich nutrients such as organic matters, amino acids, humic acid, growth hormone and the like, and various trace elements. However, the biogas slurry has low nutrient concentration, high salinity, large volume, difficult transportation, low utilization value and high treatment cost, so that the problem of seeking a safe and effective biogas slurry resource utilization mode becomes an urgent need to be solved.
The method for treating the biogas slurry by land digestion is considered to be the most easy to implement and effective biogas slurry treatment method at present, treats wastes through the combined action of crops, microorganisms and the like in land and a system, and has the advantages of large treatment capacity, low cost, good effect of removing nitrogen and phosphorus and the like. The biogas slurry is applied to the soil, so that the pH of the soil can be obviously improved, organic matters and microbial communities can be increased, meanwhile, the pest and disease damage can be prevented, the yield of crops can be increased, the quality of agricultural products can be improved, and the biogas slurry is considered to be a good soil conditioner. The farmland for dispelling the biogas slurry is mainly a paddy field, and the dry farming field is few. The existing research shows that the maximum safe biogas slurry digestion capacity of the paddy field is 300t/hm2The optimal biogas slurry digestion capacity is 75-150t/hm2. The rice prefers fertilizer and is salt and alkali resistant, a large amount of irrigation is needed in the growth period, and the biogas slurry can be fully diluted; meanwhile, the temperature is high in summer, the microbial activity is strong, the metabolism is fast, and organic pollutants in the biogas slurry can be rapidly decomposed. The method for replacing partial fertilizer with biogas slurry to be used as rice topdressing can only basically solve the problem of biogas slurry generated in summer and autumn but not in winter and spring due to the seasonality of rice growth.

The rice test variety of all examples was Nanjing 9108, harvested uniformly by machine and weighed in weighbridge. The planting area of each treated rice is 14hm2The plan view of the test piece is shown in FIG. 1.
The test time is from 11 months in 2018 to 11 months in 2019, and the test site is a salt city Huafeng farm.
TABLE 1 soil index Change at different periods
As shown in Table 1, before the start of the test, the original indexes of 3 test plots were substantially the same, and the fertility status was not greatly different. After the test is finished, the indexes of the soil of 3 test fields are obviously different, and the index of ZYJ treated soil is obviously superior to that of other 2 fields.
After biogas slurry is used for raising the field, the organic matters and available nutrients of soil treated by ZYJ are greatly improved, and the organic matters, alkaline hydrolysis nitrogen, available phosphorus and available potassium are respectively improved by 9.9%, 38.6%, 87.9% and 238%; the total salt content is greatly reduced by 22.3 percent; the pH change is not great, and the pH value is reduced by 3.5 percent.
After the test is finished, compared with the soil treated by ZCG and CK, the soil organic matter, alkaline hydrolysis nitrogen, available phosphorus and quick-acting potassium treated by ZYJ are respectively 13.2% and 13.7%, 15.1 and 32.6%, 5% and 52%, 24.7 and 42.9%, the total salt content is respectively 11.4% and 19.4% lower, and the pH value is basically consistent.
From the whole test process, the organic matter of the soil treated by ZYJ is increased by 2.2%, and ZCG and CK are reduced by 10.2% and 9.9%; the total salt content of the soil treated by ZYJ, ZCG and CK is respectively increased by 6.9%, 18.5% and 29.6%; the pH of 3 test plots was slightly lowered as a whole; the alkaline hydrolysis nitrogen of the soil treated by ZYJ is increased by 20.8 percent, and the ZCG and CK are reduced by 23.2 percent and 30.3 percent; the available phosphorus of the soil treated by ZYJ, ZCG and CK is respectively reduced by 18.3 percent, 16.8 percent and 21.2 percent; the ZYJ treated soil quick-acting potassium was substantially unchanged, and the ZCG and CK treated soils were reduced by 19.8% and 28.5%.
As can be seen from Table 2, the heavy metal content in the 3 treated soils was much lower than the risk limit of the national soil environmental quality Standard GB15618-2018, wherein the Cr, Cu and Ni content in the ZYJ treated soils decreased slightly compared to the CK treated soils.
TABLE 2 post harvest heavy metal content (mg/kg) in soil of rice
As shown in FIG. 2, the rice treated by ZYJ has vigorous growth and high yield, and is obviously superior to the rice planted by ZCG and CK treatments.
The ZYJ treatment promotes the growth of rice. The plant height of the CK-treated rice is the lowest and is only 84.2 cm. The plant heights of the rice treated by ZCG and ZYJ are respectively 95.5cm and 93.6cm, and the difference is not significant; but compared with CK treatment, the method improves the treatment efficiency by 13.4 percent and 11.2 percent respectively, and has obvious difference.
The ZYJ treatment increased the effective ear number of the rice. The effective spike of the CK-treated rice is the lowest, and only 13.4 spikes/hole are available. The number of effective spikes of the ZCG-treated rice is 14.7 spikes/hole, which is improved by 9.7 percent compared with CK treatment, but no obvious difference exists; the rice treated by ZYJ has the highest effective spike number which is 16.5 spikes/hole, and compared with CK treatment and ZCG treatment, the effective spike number is increased by 23.1 percent and 12.2 percent respectively, and the difference is obvious.
ZYJ treatment has little influence on the grain number of rice per ear, thousand grain weight and polished rice rate of rice. CK treatment is highest on rice, ZCG treatment is second, ZYJ treatment is lowest, but no significant difference exists among the CK treatment, the ZCG treatment and the ZYJ treatment.
ZYJ treatment increased rice yield. The yield of CK-treated rice is 9615kg/hm2. Compared with CK treatment, the yield of ZCG rice is slightly reduced to 9585kg/hm2Reduced by 30kg/hm2While the rice yield of ZYJ is greatly increased and is 10215kg/hm2Increased by 600kg/hm2。
As seen from Table 3, except for the reduction of copper content in the planting with biogas slurry, the application of biogas slurry can effectively increase the nutrients such as fat, protein, amino acid and the like and mineral elements such as iron, calcium, copper and zinc in the polished rice, and the sodium content is reduced. Compared with CK treatment, the fat in the refined rice treated by ZYJ is increased to 1.5g/100g, which is increased by 66.7%; the protein is increased to 8.59g/100g, which is improved by 28.2%; the amino acid is increased to 7.07g/100g, which is increased by 243.6%; mineral elements such as iron, calcium, copper and the like are obviously increased, and particularly, the calcium is increased by 94.3 times; the sodium content is reduced to 0.597mg/100g, which is reduced by 84.4%.
TABLE 3 content of nutrients in polished rice
In conclusion, the organic rice (ZYJ) is planted in a planting mode of ' biogas slurry fertilization (fallow) + organic rice ', so that the organic matter and quick-acting nutrients of soil can be improved, the soil is fertilized, the risk of salinization of the soil is reduced, the growth and development of the rice can be promoted, the yield is increased, the content of nutrient components in the refined rice of the rice is increased, the content of Ca in a mineral substance is higher than that recorded in the existing literature of the rice, after the rice is harvested, the content of heavy metals in the soil does not exceed the risk limit value in the national soil environment quality standard GB15618-2018 ', and the problem of heavy metal pollution of the soil does not exist.
