Rice is the main food crop in the red soil area of my country. However, the pH value of the farmland in the red soil hilly area is low, the soil is acidic, and the rice planting yield is not high. In the acidic red soil area, the rice field is more active, and it is more difficult to use it safely.
[0003] The existing method of acidic soil utilization mainly adopts the addition of lime powder for treatment, but using lime powder for acid treatment takes a long time for soil treatment, and a large amount of lime powder is used, which gradually causes the internal pH value of the soil to be too large, exceeding the 5% suitable for rice growth. -6pH value range, while adding lime powder for a long time, the cost is high, and the value for the subsequent growth of rice itself is limited

[0046] The test soil in Dongkou County, Shaoyang City, Hunan Province was selected, the pH value of the soil was 3.5-4, and the area was 1 mu.
[0047] Adopt the fertilization method that this application provides:
[0048] Include the following steps:
[0049] (1), collect the dead grass left over in the test soil area, burn it after drying, and collect the plant ash produced after burning;
[0050](2), filter and screen the plant ash collected above to obtain the filtered plant ash A;
[0051] (3), add A to water and mix, after cooling to room temperature, continue to add water to prepare the aqueous solution B of plant ash;
[0052] (4), select the soil area cleared in step (1), carry out planting planning to this soil area, divide the planting area, and carry out deep plowing 45cm inside the planting area;
[0053] (5), install a soil improvement structure inside the soil area after deep plowing, the soil improvement structure is inserted into the soil to a depth of 45c...

Abstract
The invention discloses a rice fertilizing method and fertilizer in an acid soil area, and belongs to the technical field of rice fertilizing planting. The rice fertilizing method in the acid soil area comprises the following steps: collecting withered grass left in the acid soil area, drying and burning the withered grass, and collecting plant ash generated after burning; performing filtering and screening to obtain filtered plant ash A; preparing an aqueous solution B of the plant ash; conducting deep ploughing in the planting area by 30-45 cm; installing a soil improvement structure in the soil area after deep ploughing is completed, and placing the aqueous solution B in the soil improvement structure; after adding is completed, carrying out film sealing on soil; after 2-3 months of film sealing, evenly spraying phosphorus-fixing soil fungi , ploughing the soil by 30-45 cm, and after ploughing is completed, leaving the soil to stand for 15-30 d; and after standing, injecting water into the soil, evenly applying fertilizer and planting rice. The fertilizer absorption capacity of rice is improved while the acid soil is improved , various microelements needed by rice growth are fully provided, and the rice yield can be greatly increased.
Description
technical field [0001] The invention belongs to the technical field of rice fertilization and planting, and in particular relates to a rice fertilization method in an acidic soil area and a fertilizer thereof. Background technique [0002] The total area of red soil in southern China is 1.2×10 6 km 2 , accounting for about 12% of the country's total land area, is an important economic crop and food crop planting area in the country. Rice is the main food crop in the red soil area of my country. However, the pH value of the farmland in the red soil hilly area is low, the soil is acidic, and the rice planting yield is not high. The rice field in the acidic red soil area has a high activity, and it is more difficult to use it safely. [0003] The existing method of acidic soil utilization mainly adopts the addition of lime powder for treatment, but using lime powder for acid treatment takes a long time for soil treatment, and a large amount of lime powder is used, which g...
