Description
Technical Field
The invention belongs to the technical field of soil conditioner preparation, and relates to a preparation method and application of a shell powder organic fertilizer biological conditioner, in particular to application of the shell powder organic fertilizer biological conditioner in continuous cropping greenhouse soil remediation.
Background
Greenhouse vegetable production is a vegetable production mode for artificially creating a vegetable environment suitable for the life when the temperature is not suitable, and the greenhouse vegetable production is popular among people at home and abroad because seasonal limitation of vegetable production is broken, and the annual supply of vegetables is balanced. The vegetable cultivation method has the characteristics of capability of supplying the demand of people on vegetables in off seasons, high yield and high efficiency, so that the vegetable cultivation method is rapidly aroused in vast suburbs in recent years and becomes a post industry in some areas. However, vegetable greenhouse production is a very strong mode of land action by human action, and the human interference not only changes the microclimate environment for vegetable growth, but also influences the soil property. The problems of hardening and secondary salinization of soil, nitrate accumulation, soil nutrient unbalance, reduction of soil enzyme activity, obvious soil acidification, damage of microbial population, enrichment of pesticide residue and the like exist in a plurality of current greenhouses. These problems seriously affect soil quality, cause a decrease in vegetable yield, deterioration in quality, and restrict sustainable use of land. Under the ecological environment condition, such as continuous cropping for many years, unreasonable fertilizer and water management and the like, a series of problems of deterioration of physicochemical and biological properties of certain soil, obvious continuous cropping obstacles, increase of soil-borne diseases and insect pests, low yield, poor quality and the like are easily caused, and the sustainable development of facility agricultural production is seriously influenced. The main reason is that the closed structure has high temperature and humidity, less incident natural light, lack of rain water for leaching, large fertilizing amount, long-term continuous cropping, serious soil degradation and greatly increased density of pathogenic bacteria.
China has abundant shellfish resources, various shellfish are developed mainly by processing edible parts of the shellfish, a large number of shells are discarded as garbage while the edible parts are utilized, and organic matters remained in the discarded shells are rotten and smelly in the long-term stacking process, so that the environment is seriously polluted. At present, shells have great application value in the aspects of medicine, medical health product development, preparation of various additives in light industry and the like. The soil conditioner developed by taking shell powder as a main raw material is not common in China. At present, the soil conditioner products on the domestic market generally adopt mineral products such as potassium feldspar, limestone and ground phosphate rock and food industry leftovers such as monosodium glutamate fermentation tail liquid as basic raw materials, and have the characteristics of single raw material, low nutrient content, poor product stability, low product added value and the like.
Therefore, how to solve the above problems is an important research content for those skilled in the art.

Further, in the step A, the washed and dried shells are pulverized into coarse micro powder of 0.1-1mm by a high-speed pulverizer or a ball mill.
The invention also provides application of the shell powder organic fertilizer biological conditioner in continuous cropping greenhouse soil remediation.
Taking planting of tomato as an example, the application technology of the shell powder organic fertilizer biological conditioner is described below.
1. As base fertilizer
The shell powder organic fertilizer biological conditioner is applied to seedling fields and garden fields as a base fertilizer. The fertilizer is applied before sowing and planting, the amount of organic fertilizer can be properly increased by the base fertilizer, and a small amount of fertilizer is supplemented. For seedling lands, the organic fertilizer and the upper layer of seedling soil are generally mixed uniformly, and the shell powder organic fertilizer biological soil conditioner is applied to the upper layer of seedling soil with the thickness of about 20 cm. For garden soil, because tomatoes have long growth periods in garden soil and have larger fertility demand, the application amount in garden soil needs to be increased. Generally 10t/667m should be reached2And a certain fertilizer is added in the later period, so that the normal growth requirement of the tomatoes can be met.
2. As top dressing
During the growth process of tomatoes, the demand of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer is different. The fertilizer efficiency of the shell powder organic fertilizer biological conditioner is slowly released, and certain nitrogen, phosphorus and potassium fertilizers are added to meet the normal growth requirement of the tomatoes. Under normal conditions, the total amount of nitrogen, phosphorus and potassium fertilizers required by the tomatoes is about 3: 1: 5, and the fertilizer has the highest utilization rate when the fertilizer is applied according to the ratio. If the fertilizer supply is insufficient, the tomatoes can grow badly, and pests and diseases can be caused, so that the yield and the quality of the tomatoes are reduced; on the other hand, it may cause excessive growth and decrease the yield. Therefore, the fertilizer is applied in a proper amount. The top dressing is applied for the first time in the first cluster fruit expanding period, and the top dressing is respectively applied for 5 times after the full fruit period. The application of the shell powder organic fertilizer biological conditioner can be properly advanced, and hole application is generally adopted for top application.
3. As top dressing for foliage
After the tomatoes enter the full-bearing period, the fertilizer absorbing capacity of the root system is reduced, foliage spraying can be carried out at this stage, and the common method is to spray 60-80 kg of 10% shell powder organic fertilizer biological conditioner leachate per mu each time, 5-7 days per time and 2-3 times continuously, so that the tomato fruit cracking can be prevented, the plant senescence can be delayed, and the harvesting period can be prolonged.
The shell powder organic fertilizer soil conditioner prepared by the method is used for testing.
The test area is a vegetable greenhouse of vegetable science research institute in Nantong city, the crops planted in the test area are tomatoes, and five treatments are set in the test and respectively comprise:
comparison: CK;
treatment 1: pure organic fertilizer;
and (3) treatment 2: 1: 1 of shell powder and organic fertilizer;
and (3) treatment: 1: 2 of shell powder and organic fertilizer;
and (4) treatment: the shell powder and the organic fertilizer are 1: 0.5;
the amount of the shell powder organic fertilizer soil conditioner applied is 60 kg/mu. The two areas are separated by furrows.
The sampling time is 2016, 4, 26, 5, 13 months, 4, 14, 8, 5, 25 months, respectively for the growth period, the flowering period and the fruit setting period.
The test results are as follows:
1. physical and chemical shape of soil
The fertilization area and the control area have different physicochemical factors in three periods of crop growth, and the table 1, the table 2 and the table 3 are average values of the physicochemical factors of different treatments in each period of soil sampled for the first time. Table 4, Table 5 and Table 6 show the average values of the different physical and chemical factors of the soil sampled for the second time in each period.
TABLE 1 physical and chemical properties of soil in growing period (1)
TABLE 2 soil physicochemical properties in flowering phase (1)
TABLE 3 physical and chemical properties of fertile period soil (1)
TABLE 4 physical and chemical properties of soil in growing period (2)
TABLE 5 soil physicochemical Properties in flowering phase (2)
TABLE 6 physical and chemical properties of fertile soil (2)
From the average value, the difference between various physical and chemical indexes of the soil in the control area and the fertilization area in the growth period of the crops is not obvious; in the flowering period of crops, the total nitrogen and the quick-acting phosphorus in the control area are higher than those in the fertilization area, wherein the treatment level 3 reaches the lowest level, the treatment level is 2 times lower, and the pH value and the organic matter are just opposite; by the time of the fruit setting period of the crops, the pH value and organic matters are higher in the fertilization area than in the control area, the treatment 3 reaches the highest level, and the treatment 2 is not obvious in difference among treatments of the quick-acting potassium. Wherein, the total nitrogen and the quick-acting phosphorus are almost consistent with the conditions of the fruit setting period and the flowering period. With the continuous growth of crops, the shell powder organic fertilizer soil conditioner promotes the absorption of nitrogen and phosphorus by the crops, so that the content of nitrogen and phosphorus in the soil is reduced. In addition, calcium carbonate exists in the shell powder organic fertilizer soil conditioner, and hydrogen ions in soil are neutralized, so that the acidification of the soil is prevented, the pH value of the soil is maintained at a stable level, and the problem of acidification of greenhouse soil is solved.
2. Soil enzyme activity
All biochemical reactions in soil are actually carried out under the participation of enzyme, and the intensity of the activity of the soil enzyme reflects the intensity and direction of various biochemical reaction processes in the soil.
TABLE 7 soil enzyme Activity in growth phase (1)
TABLE 8 soil enzyme Activity during flowering phase (1)
TABLE 9 soil enzyme Activity during fruit set period (1)
TABLE 10 soil enzyme activity in growth phase (2)
TABLE 11 soil enzyme Activity during flowering phase (2)
TABLE 12 soil enzyme Activity during fruit set period (2)
As can be seen from the above table, the four enzyme activity control zones are not much different from the four treated fertilization zones during the growth period of the crop.
During the flowering period of crops, the urease activity of the four treatment fertilization areas is greatly lower than that of the control area, soil urease is a hydrolase acting on urea fertilizer, urea can be hydrolyzed into ammonia and carbonic acid, and a nitrogen source is directly provided for the crops, but if the urease activity is too high, the toxicity of nitrite and ammonia is caused, urea nitrogen is lost in a gaseous state in the form of ammonia, and therefore the urease activity is preferably maintained at a proper level. Tables (7-12) show that the change in soil urease activity for the control and treated fertilisation zones had the same trend. Urease activity gradually increased over time, reaching a maximum during fruit set. The activity of the root system in the soil is vigorous along with the growth of crops, so that the secreted urease is increased, and the urease activity is increased. However, the urease activity of the soil conditioner added with the shell powder organic fertilizer rises more smoothly, so that the components in the conditioner have a certain inhibition effect on the urease activity and are beneficial to the growth of crops. Where process 3 has the smallest rise magnitude.
Amylase activity four fertilization zones were higher than the control zone, and amylase was able to hydrolyze glycosidic bonds in starch. The mean values in the table show that the amylase activity in the control zone was consistently elevated, as were the four treated fertilisation zones, but the magnitude of the post anthesis rise began to decrease. The method also shows that the vigorous growth period of crops is also the period of the most active soil amylase, and the application of the shell powder organic fertilizer soil conditioner has a certain effect on improving the activity of the amylase in the period which is presumed from the enzyme activities of the soil in the control area and the four treatment fertilization areas, wherein the improvement of the treatment 3 is more obvious than that of the treatment 2 and the treatment 4.
The activity of the sucrase is also that the four fertilizing areas are higher than the control area, the sucrase can hydrolyze sucrose into glucose for microorganisms and the like, and the sucrase can reflect the conversion and absorption intensity of carbon in soil. After the conditioner is applied, the enzyme activity is always increased, and the enzyme activities of the treatments 2, 3 and 4 are always slightly higher than those of the control area and the treatment 1, so that the conditioner improves the activity of soil sucrase to a certain extent. The improvement effect of treatment 3 is more obvious than that of treatments 2 and 4.
Catalase activity four treatment fertilization zones are slightly higher than the control zone, and catalase can decompose hydrogen peroxide which can poison soil and organisms. The catalase activity of the soil in the control area and the fertilization area is always increased, but the increase is small.
The variation trend of the activity of urease, amylase and sucrase in the fruit setting stage is basically consistent with that in the flowering stage. Urease treatment was only 3 higher than the control zone.
3. Microbiological condition of soil
Soil fertility is closely related to soil microorganisms, and many enzymes in soil are secreted by soil microorganisms. The quantity of bacteria, actinomycetes and fungi in the soil can represent the soil fertility and is one of the evaluation indexes of the soil fertility. The test mainly clarifies the effect of the shell powder organic fertilizer biological conditioner on improving the ecological environment of greenhouse soil by detecting the quantity change of fungi, bacteria and actinomycetes in the rhizosphere soil of tomatoes.
TABLE 13 microbial count of soil in growing period (1)
TABLE 14 microbial count of soil at flowering time (1)
TABLE 15 microbial count of fertile soil (1)
TABLE 16 microbial count of soil in growing period (2)
TABLE 17 microbial count of soil at flowering time (2)
TABLE 18 microbial count of fertile soil (2)
The average values in the table show that in the growth period of crops, the three types of bacteria of treatment 1, treatment 2 and treatment 3 have no significant difference, and are slightly higher than the treatment 4, and the fertilization area is slightly higher than the control area. The application of the shell powder organic fertilizer biological conditioner is presumed to improve the soil microbial activity.
In the flowering period, the fungi and bacteria of the treatment 1, the treatment 2 and the treatment 3 have no significant difference, and are slightly higher than the treatment 4, and the four treatment fertilization areas are slightly higher than the control area. There were significant differences in actinomycetes.
By the fruit setting period, the rhizosphere bacteria in the control area and the four treated fertilization areas are obviously different, which is probably because the pH value of the soil in the control area is reduced, the soil is acidified, the bacteria are prevented from breeding, and the bacteria number in the control area and the fertilization areas is different.
Rhizosphere soil bacteria in the control area show a trend of rising from a growth period to a flowering period and falling after the flowering period, while the four treatment fertilization areas show a trend of rising from the growth period to a stable flowering period, namely, the pH of soil in the control area begins to fall at the later growth stage of crops, so that the propagation of the bacteria is prevented, and the pH is maintained in a neutral and alkaline environment by applying the shell powder organic fertilizer biological conditioner, so that the control area is suitable for the mass propagation of the bacteria. The number of rhizosphere actinomycetes in the fertilization area shows a trend of increasing all the time, because certain components in the shell powder organic fertilizer biological conditioner are beneficial to the growth of actinomycetes, the levels of actinomycetes of treatment 2, treatment 3 and treatment 4 are always higher than that of treatment 1, and the level of actinomycetes of treatment 3 is the highest; the rising amplitude from the flowering period to the fruit setting period is lower than that of the control area, because the quantity of rhizosphere soil bacteria in the fertilizing area in the fruit setting period is increased, so that the survival competitive pressure of actinomycetes is increased, but the quantity of the actinomycetes is always higher than that of the control area in general.
According to the invention, the shell powder and the organic fertilizer are combined to replace industrial fertilizers, and the biotechnology and the new material preparation technology are combined, so that the soil structure and physical properties can be improved, the water and fertilizer retention capacity of the soil can be improved, the microbial population of the damaged soil can be recovered, and the vegetable diseases can be reduced, thereby achieving the purposes of high yield, high quality, high efficiency and continuous utilization of the soil in vegetable production.
The shell powder organic fertilizer soil conditioner can promote crops to absorb nutrient elements, particularly nitrogen and phosphorus, improve the content of soil organic matters, properly improve the pH of soil, prevent secondary salinization and acidification of greenhouse soil, effectively improve the ecological environment of the greenhouse soil, and has important significance for sustainable cultivation of the greenhouse soil. Meanwhile, the shell powder organic fertilizer soil conditioner can influence the enzyme activity of soil, inhibit the urease activity, maintain the urease activity at a proper level, avoid the accumulation of N and improve the utilization rate of urea; the shell powder organic fertilizer soil conditioner also improves the activity of soil amylase, is beneficial to the decomposition of polysaccharide substances in soil and provides more nutrients for plants; the activity of the sucrase is also improved, the hydrolysis of the sucrose into glucose is promoted, a carbon source is provided for soil microorganisms, and the activity of the soil microorganisms is enhanced, so that the sucrase is beneficial to the growth of crops. In addition, the shell powder organic fertilizer soil conditioner effectively improves the microbial condition of soil, increases the quantity of rhizosphere bacteria and actinomycetes of crops, and the activity of the rhizosphere microorganisms is beneficial to generating more soil enzymes, enhances the absorption of the crops on nutrient elements and effectively promotes the growth of the crops.
