Problems solved by technology

However, the current method of mulching peanuts with plastic film is only suitable for the cultivation of spring-planted peanuts in South China, and the technology of plastic-film mulching cannot be applied to autumn-planted peanuts.
South China is a subtropical region, and the climate is hot in late summer and early autumn. Autumn planting peanuts are generally sown about 10 days before and after the beginning of autumn in early August. Burning, failure to germinate and grow properly, leading to harvest loss
This is the main reason why the widely used peanut mulching technology is difficult to apply to the production of autumn peanuts in subtropical regions

Embodiment 1

[0037] Such as figure 1 As mentioned above, the punching device includes two beams 1 and two row spacing fixing rods 2, and each beam 1 is equipped with 4 punchers 6; the same end of the two row spacing fixing rods 2 has a short hole slot respectively. 4. The row spacing adjustment screw 3 is located in the short hole slot 4; the two row spacing fixing rods 2 are respectively located at both ends of the beam 1, and the distance between the two beams 1 is adjusted through the row spacing adjustment screw 3. The two beams 1 and The two row spacing fixing rods 2 are rectangular and kept on the same level; each crossbeam 1 is provided with a long hole slot 5, and the distance between plants adjustment screw 10 is located in the long hole slot 5; The beams 1 are connected and fixed; a handle 11 is installed at the end of each beam 1 respectively. Such as Figure 2~4 Shown, each puncher 6 is a hollow cylinder, the lower end is a circle of sawtooth 8, and the upper end is equipped ...

Embodiment 2

[0039] The variety used in this example is Yueyou No. 7, and the soil type of the test site is partial sticky loam, which was previously used as rice. Two planting methods were set up in the experiment: plastic film mulching cultivation and open field cultivation, and the planting area of ​​each method was 0.3 mu.

[0040](1) Soil preparation and fertilization: Both planting methods adopt a one-time fertilization method. Before planting, the fertilizer is evenly spread before the soil preparation, and the soil is deeply plowed and loosened by more than 30cm, and it is turned into the cultivation layer, and the two plows and multiple harrows are used to level off. The amount of fertilizer applied is 2000 kg of miscellaneous fertilizers per mu, 15 kg of urea, 30 kg of superphosphate, and about 15 kg of potassium chloride. The general requirement for soil preparation is finely crushed and leveled, avoiding large clods, so as not to affect the effect of covering film. Ditch the f...

Abstract

The invention discloses a plastic film mulching cultivation method suitable for autumn-planted peanuts in subtropical regions. The method is as follows: carrying out soil preparation as soon as possible after harvesting previous crops, combining the oil preparation with fertilization together, and adopting the one-time fertilization way; firstly mulching a film for covering the soil before seeding, and utilizing the high temperature in late summer or early autumn in the subtropical regions for killing partial pathogens, weeds and pests in the soil; adopting the technology of firstly punching and then seeding, and seeding peanut seeds in holes without covering the seeds in the plastic film for preventing the high temperature from baking the seeds; adopting the technology of sequentially covering the soil, the seeds and the film for preventing hot airflow in the film from escaping and burning seedlings; and simultaneously effectively reducing water content in the soil after heavy rain and being conductive to the germination of the peanut seeds. The method is simple, practical, easy to master and convenient to popularize, and can solve the problem that the plastic film mulching technology can not be applied in the autumn-planted peanuts in the subtropical regions, significantly improve the output of the autumn-planted peanuts in the subtropical regions and be particularly applicable to the cultivation of the autumn-planted peanuts in dry land and rain-fed fields in rain-fed areas of the subtropical regions.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a film-covered cultivation method suitable for autumn planting of peanuts in subtropical regions. Background technique [0002] Plastic film mulching cultivation is a technology that covers the land where crops are planted to increase soil temperature, maintain soil moisture and nutrients, and achieve the purpose of increasing crop yield and improving product quality by creating a soil ecological environment more suitable for crop growth. Peanut is a crop that blooms on the ground and bears fruit underground. It takes a long time for the pods to grow and mature in the soil and is greatly affected by soil temperature, water and nutrients. Therefore, plastic film mulching has a great impact on the yield and quality of peanuts. The test results show that, compared with open-field cultivation, peanut mulching cultivation can mature 10-15 days earlier and increase...
