[0002] Existing agricultural plastic films are difficult to decompose under natural conditions, have low tensile strength, are easy to break, are not easy to recycle, and pollute the soil. Therefore, in recent years, in order to reduce the damage to the soil caused by high-plastic mulch films such as polyethylene, people have begun to use alternative products to mulch films - agricultural paper films. Agricultural paper films are made of waste paper and crop straw. They are thick and have a certain light-shielding property. They are easy to decompose themselves, and the decomposition products have no effect on the soil. Agricultural paper films are an environmentally friendly product that replaces agricultural plastic films. They are an important measure to achieve the goal of replacing plastic with paper and protecting farmland and agricultural products from microplastic pollution.

[0048] When preparing paper film for planting crops, oysters and scallops are crushed and ground to 60 nm in a mass ratio of 1:1 to obtain organic nanomaterials; the remaining parameters and preparation steps are the same as those in Example 1.
[0049] Example 4
[0050] The paper film for planting crops prepared in Example 1 was subjected to a field test. On May 14, 2024, a 6-acre rice film planting test was conducted in Ehu Town, Sanxin Village, Wuxi City, Jiangsu Province. The rice variety used was the variety Nangeng 1176. The Vinasi and bacterial solution used in the planting test were both from Shanghai Hongbao Green Aquatic Products Co., Ltd. The control plots were planted with conventional rice sowing, and the rest of the steps were the same as the experimental plots.
[0051] Here is the planting process:
[0052] On May 14, we started raising rice seedlings, with 50 kilograms of rice seeds and 180 seedling trays.
[0053] On May 15th, the first watering of the rice fields with Vinashi and bacterial liquid began at 5 a.m.
[0054] On May 21, Yiyeyixin watered the plant with Vinashi and bacterial solution for the second time.
[0055] On May 25, the second leaf and one core were watered with Vinashi and bacteria solution for the third time.
[0056] On June 1, Sanye Yixin was watered with Vinashi and bacteria solution for the fourth time.
[0057] On June 12, three days before transplanting, the fifth watering of Vinashi and bacterial solution was carried out.
[0058] On June 14, rotary tillage and fertilization began on the experimental fields where film-covered rice seedlings were planted. 50 kilograms of compound fertilizer were used per mu, and a total of 300 kilograms of compound fertilizer (Heart-to-Heart compound fertilizer, total nutrients nitrogen, phosphorus and potassium 45%) were used.
[0059] On June 15-16, rice seedlings were transplanted, and the experimental plots were planted using both the transplanting method on the film and the direct seeding method on the film.
[0060] On June 18, due to the unevenness of the land after the water was drained, the paper film in the middle without water was blown away by strong winds, covering an area of about 10 square meters.
[0061] On June 19, it rained during the plum rain season and the overflow outlet was built to maintain the water level.
[0062] On June 27, it was observed that the growth was good.
[0063] On July 3, fertilizer was applied for seedling tillering. A total of 120 kilograms of urea were applied to 6 mu of land (the traditional dosage is 30 kilograms / mu), and Vinashi and bacterial solution (50 grams / mu of Vinashi, a total of 300 grams, 500 milliliters of bacterial solution / mu, a total of 3000 milliliters) were sprayed. 100 kilograms of well water was added for dilution and then sprayed by drone.
[0064] On July 15, the rice paper film in the experimental field began to decompose, and the weed control effect of the paper film was obvious. There were a few weeds between the two films.
[0065] On July 28, 120 catties of urea (20 catties / mu) was sprayed on 6 mu of experimental field.
[0066] On July 31, the 6-mu experimental field began to be watered and dried for a week, then exposed to the sun until the ground cracked, to promote root growth.
[0067] On August 16, rice in the experimental field began to enter the heading stage, with small grains inside the stems.
[0068] On August 20, 50 grams of Vinashi elements and bacterial solution (at the booting stage) were sprayed per mu, totaling 300 grams, and 500 milliliters of bacterial solution per mu, totaling 3000 milliliters) were added to 100 kilograms of well water for dilution and then sprayed by drone.
[0069] On August 22, the rice in the experimental fields began to enter the heading stage.
[0070] On August 30, the flowering period began.
[0071] On September 8, the rice began to fill with grain.
[0072] On September 26, the rice entered the milky stage.
[0073] On October 7, the rice entered the waxy stage.
[0074] On October 29, rice harvesting began.
[0075] Depend on Figure 1 It can be seen from the color of the rice husk surface that the rice planted on the film is more golden in color, enters the waxy stage earlier, and shortens the growth period of wheat. Figure 1 The left side in the middle shows the experimental field where rice is planted on film, and the right side shows the control field where rice is planted using the traditional method.
[0076] On October 14, the rice plant height, ear length, number of spikelets, and number of grains per ear were tested in the experimental and control plots. Figure 2~3 As shown in Tables 1 to 3.
[0077] Table 1 Traditional rice varieties in Sanxin Village
[0078]
[0079] Table 2 Rice seeding on plastic film in Sanxin Village
[0080]
[0081] Table 3 Direct seeding of rice on plastic film in Sanxin Village
[0082]
[0083] As shown in Tables 1-3, after testing the agronomic traits of rice in three different planting methods, it was found that the average plant height of traditional sowing was 80.71 cm, the average ear length was 16.37 cm, the average total number of grains per ear was 150, the average number of filled grains was 136.4, the average number of blighted grains was 13.8, and the fruit setting rate was 90.9; the average plant height of film-inserted sowing was 90.48 cm, the average ear length was 17.03 cm, the average total number of grains per ear, the number of filled grains, the number of blighted grains and the fruit setting rate were 159, 150.4, 8.6 and 94.57% respectively; the average plant height and ear length of direct sowing on film were 90.26 cm and 17.15 cm respectively, and the average total number of grains per ear, the number of filled grains, the number of blighted grains and the fruit setting rate were 162.2, 153.7, 8.2 and 94.64% respectively.
[0084] Compared with the traditional planting method, the plant height of the film-inserted seeding and the film-direct seeding increased by 9.77 cm and 9.55 cm, respectively, the average ear length increased by 0.66 cm and 0.78 cm, respectively, the average number of full grains increased by 14 and 17.3, respectively, and the average number of blighted grains decreased by 5.2 and 5.6, respectively. It can be seen that after using the paper film for crop planting prepared by the present invention, the plant height, ear length, and number of grains per ear of rice are increased, and the number of blighted grains is significantly reduced.
[0085] Depend on Figure 2 It can be seen that the plant height and ear length of the planting mode on film and the direct seeding mode on film in the experimental field are better than those of the traditional planting mode in the control field. Figure 2 From left to right in the figure are the traditional planting mode, the film-inserted planting mode, and the film-direct seeding planting mode.
[0086] Depend on Figure 3 It can be seen that the grain length and width of the planting method on the film in the experimental field are better than those of the traditional planting mode in the control field and the direct seeding on the film in the experimental field. Figure 3 From top to bottom in the figure are traditional planting mode, film-inserted planting mode, and film-direct seeding planting mode.
[0087] The yield test was conducted on October 29th. The planting area of the rice seedlings planted on the film was 5.6 mu, the actual harvest weight was 6560 catties, the actual moisture content was 31%, the standard moisture content of japonica rice was 14.5%, and the final calculated yield per mu was 945.36 catties.
[0088] In rice processing, 2,103 kg of paddy and 1,350 kg of rice were produced, with a final rice yield of 64.19%, which is an increase compared to the 50-60% yield of traditional planting methods.
[0089] Example 5
[0090] The rice harvested in Example 4 was tested according to the national standard GB1354-2018. The test content included nutrients, mycotoxins, pollutants, and 222 pesticide residues in the rice. The test results showed that all indicators in the rice met the national standards, ensuring the safety and health of the rice. And in the 222 pesticide residue tests, no pesticide residues were detected (including α-hexachloride, imidacloprid, pretilachlor, trichlorfon, dichlorvos, boscalid, carbendazim and other pesticides, and the specific test report results are shown in other supporting documents). Among them, the inorganic impurity content and the yellow rice content mixing rate are both zero, and aflatoxin B1 and ochratoxin A in the fungal toxins are not detected. The detection content of lead, total mercury, chromium and benzo[a]pyrene in the heavy metal pollutant test is zero. The results of the nutrient and bensulfuron residue tests are shown in Table 4 below.
