Embodiment 1

[0013] Embodiment 1 Spring sowing large peanut field test

[0014] Sowing on April 28, sowing method:

[0015] Experimental group: when sowing, put two seeds side by side in the sowing ditch upright, with the radicle 2 facing down, and make the joint 1 of the two cotyledons parallel to the ridge (such as figure 1 , figure 2 shown), the two holes on the ridge are staggered sowing peanuts (such as image 3 shown).

[0016] Control group: the traditional sowing method was adopted, two seeds were randomly placed flat in the sowing ditch, and the positions of the peanuts in the two holes on the ridge were opposite (such as Figure 4 shown).

[0017] The remaining conditions of the experimental group were the same as those of the control group. The ridge distance of the test field was 85 cm, the width of the ridge surface was 55 cm, two rows of peanuts were sown on the ridge, the distance between the holes was 30 cm, and the hole distance was 16.5 cm. Two seeds were planted in ...

[0021] Embodiment 2 field test of small peanuts sown in spring

[0022] Sowing on May 2, sowing method:

[0023] Experimental group: When sowing, put two seeds side by side in the sowing ditch, with the radicle facing down, and make the joints of the two cotyledons parallel to the ridge direction, and sow peanuts in two holes on the ridge.

[0024] Control group: the traditional sowing method was adopted, two seeds were randomly placed flat in the sowing ditch, and the peanuts in the two holes on the ridge were opposite to each other.

[0025] The remaining conditions of the experimental group were the same as those of the control group. The ridge distance in the test field was 85 cm, the ridge width was 55 cm, two rows of peanuts were sown on the ridge, 30 cm apart, and the hole distance was 16 cm. Two seeds were planted in each hole. The variety is the pearl bean-shaped peanut Huayu No. 20.

Abstract

The invention discloses a planting method for increasing peanut yield. The planting method comprises the step of seeding, wherein two seeds are vertically planted in a seeding ditch in parallel, embryonic roots are downward, the butt seam of two cotyledons is parallel to a ridge, and two holes of peanut are seeded on the ridge in a staggered manner. According to the invention, by changing the seeding method of seeds, two cotyledons are parallel to the ridge after peanut seedling emergence, so that first pair of lateral branches grown from the cotyledon node are both vertical to the ridge, and are trim and consistent; and at the same time, peanut is planted on the ridge in the staggered manner, thus the formed colony structure is favorable to increasing light transmittance and gas exchange in canopy, increasing photosynthetic efficiency of the canopy and further increasing legume yield. Tests prove that by adopting the method to plant peanut, the peanut seedling emergence is advanced by 1-2d as compared with routine seeding, the CO2 concentration and light transmittance at the roots of the plants on the ridge are increased by 2.2-7.6% and 9.6-12.3%, respectively, the photosynthesis intensity of the canopy is increased by 8.7-12.8%, and the legume yield is increased by 8.7-13.4%. Therefore, the planting method can obviously increase peanut yield.

Description

technical field [0001] The invention relates to a planting method for improving peanut yield, and belongs to the field of agricultural technology. Background technique [0002] At present, the traditional film-covered cultivation method of peanuts is that two seeds are randomly placed flat in the sowing ditch, and the peanuts in the two holes on the ridge are opposite to each other. Although this sowing method is convenient, its peanut yield is not ideal. Its reason: the one, it takes a long time to emerge, and the seed radicle first bends downwards after breaking through the seed coat, and then grows downwards, and the two cotyledons need to be changed from a horizontal state to an upright state (radicle is facing down) in the soil. The planting process is time-consuming and consumes nutrients, resulting in slow emergence, weak growth of seedlings after emergence, and poor uniformity of emergence, which directly affects the quality of future populations. The second is tha...
