Problems solved by technology

Although traditional chemical fertilizers have a certain lethal effect on snails, large-scale application of chemical fertilizers will also cause serious pollution to soil and water bodies, leading to aggravation of eutrophication in water bodies; and the use of chemical molluscicides to kill snails will also harm aquatic organisms such as fish. cause poison

Embodiment 1

[0054] Example 1 Morphological distribution and main components of calcium oxalate needle crystals.

[0055] Table 1 is a comparison table of the distribution of calcium oxalate needle crystals in plant tissues and organs in the main plants of Araceae and Amaryllidaceae. It can be seen from the results in Table 1 that calcium oxalate needles are most distributed in plant tubers and bulbs.

[0056] Figure 1~4 It shows the calcium oxalate distribution and main morphology of representative plants of Araceae and Amaryllidaceae. It can be seen from these diagrams that the morphology of needle crystals of different species of plants is different. In addition, the present invention also carries out electron scanning microscope observation to the calcium oxalate needle crystal in a umbrella Nanxing tuber, as Figure 5 As shown in the figure, its structure is needle crystal, which is needle-shaped and has grooves on the side. The needle-like structure may cause mechanical damage to ...

Embodiment 2

[0063] Verification example of molluscicidal effect of plant calcium oxalate needle crystals of the present invention.

[0064] (1) Extraction and separation of calcium oxalate needle crystals:

[0065] (i) Washing, drying, grinding, and storing the tuber of a umbrella southern star plant for subsequent use;

[0066] (ii) After mixing the tuber and water evenly in a ratio of 1: (2-3), grind for 2-3 hours, centrifuge, control the speed of the centrifuge to 500-1200rpm, then separate, take the supernatant, and air-dry, Store at 3-5°C for later use.

[0067] According to the above-mentioned separation and extraction method, the calcium oxalate needle crystals obtained are mixed with nitrogen fertilizer, phosphorus fertilizer, and potash fertilizer respectively to make the compound molluscicide preparations ANF, APF, AKF and ACF, and then the snail killing experiment was carried out using the soaking standard recommended by WHO, and the snails were treated with different concent...

Embodiment 3

[0069] Effects of compound molluscicide preparations on rice seed germination and seedling growth.

[0070] By the same method as in Example 2, the compound molluscicide preparations ANF, APF, AKF and ACF with respective raw material concentrations of 0.25 g / L and 0.5 g / L were prepared respectively.

[0071] The above-mentioned compound molluscicide preparations were soaked to treat the rice seeds respectively, and placed in an artificial climate box for cultivation. 12 hours of light at 30°C and 12 hours of darkness at 25°C in a climate box with an illumination of 6000LX. The observation and statistical results of the compound snail-killing fertilizer preparation on the germination of rice seeds are as follows: Figure 7 Shown, show that ANF, APF and AKF (concentration is 0.25g / L) obviously promote seed germination and seedling growth, and wherein the promoting effect of ANF is more remarkable: the germination rate of 3 days and 5 days has improved 25% and 21% ; The growth ...

Abstract

The invention relates to a plant source organic-inorganic compounding molluscicide fertilizer preparation and a preparation method and application thereof, and relates to the technical field of biological pesticides. The plant source organic-inorganic compounding molluscicide fertilizer preparation comprises a needle-like calcium oxalate crystal and an inorganic fertilizer, wherein the needle-likecalcium oxalate crystal is obtained by separating and extracting from a plant of Araceae or Amaryllidaceae. The plant source organic-inorganic compounding molluscicide fertilizer preparation also preferably includes a plant fermented organic fertilizer. A suitable amount of chemical fertilizer is added to a needle-like calcium oxalate crystal extract contained in the plant of Araceae and Amaryllidaceae, and a plant extract residue fermented product is used as an organic fertilizer carrier to prepare the plant source organic-inorganic compounding molluscicide fertilizer preparation. The plantsource organic-inorganic compounding molluscicide fertilizer preparation can not only promote rice growth, increase yield, also has the effect of killing snails and achieve the double effect of killing Oncomelania hupensis to achieve the integration of double effects of molluscicide and fertilizing. In addition, the plant source organic-inorganic compounding molluscicide fertilizer preparation issimple in preparation method, the production cost is low, the use is convenient, and the plant source organic-inorganic compounding molluscicide fertilizer preparation is conductive to large-scale application and promotion in a rice field in a schistosomiasis epidemic area.

Description

technical field [0001] The invention relates to the technical field of biopesticides, and more specifically, the invention relates to a plant-derived organic-inorganic compound molluscicide preparation and its preparation method and application. Background technique [0002] Schistosomiasis is the most important parasitic disease that seriously endangers people's health and life safety and affects economic and social development. There are 74 countries and regions in the world where schistosomiasis is endemic, with a population of 600 million in endemic areas and 200 million people infected. Millions of patients died of schistosomiasis. [0003] The inventor found during the investigation and visits in the epidemic areas that during the cultivation and management of rice fields, people in the epidemic areas were repeatedly infected due to paddy field cultivation, so it is more hoped that the molluscicide can also be used to fertilize rice. . Although traditional chemical f...
