Problems solved by technology

Mixed sowing of different varieties can increase the amount of light energy intercepted by the wheat canopy, but the quality of wheat of different varieties is mixed after harvesting, and the taste of the milled flour is uneven. Although the yield has increased, the quality has declined, so the actual production It is not meaningful
Laying reflective panels on the ground will greatly increase labor intensity and wheat production costs. It is time-consuming and labor-intensive in production, which is relatively rare and only found in scientific research literature

Embodiment 1

[0027] The autumn of 2012 carried out the traditional flat furrow planting method (the sowing width is 150cm, planting 10 rows of wheat, and the sowing rate is 10 kg / mu) and the comparative test of the present invention in Jinhai Seed Industry Co., Ltd., Laizhou City, Shandong Province.

[0028] A kind of cultivation method of improving wheat light energy interception of the present invention, arable land is set as the furrow structure of wide and narrow row.

[0029] Ridging 2 of the wide row of cultivated land, ditch 5 of narrow row.

[0030] Ridge 2 is 8cm wide, and ditch 5 is 5cm wide.

[0031] The height difference between the ridge top 3 and the ditch bottom 6 is 8cm.

[0032] One row of wheat is planted at the top of the ridge 3, and two rows of wheat are planted at the bottom of the ditch 6.

[0033] Ridge top 3 planting wheat 4 seeding depth is 6cm, ditch bottom 6 planting wheat 4 planting depth is 4cm, ridge top 3 and ditch bottom 6 planting wheat 4 seed height dif...

Embodiment 2

[0041] In the autumn of 2018, the repeat verification test of the present invention was carried out in the experimental field of the Crop Research Institute of Shandong Academy of Agricultural Sciences:

[0042] A kind of cultivation method of improving wheat light energy interception of the present invention, arable land is set as the furrow structure of wide and narrow row.

[0043] Ridging 2 of the wide row of cultivated land, ditch 5 of narrow row.

[0044] Ridge 2 is 10cm wide, and ditch 5 is 7cm wide.

[0045] The height difference between the ridge top 3 and the ditch bottom 6 is 10cm.

[0046] One row of wheat is planted at the top of the ridge 3, and two rows of wheat are planted at the bottom of the ditch 6.

[0047] Ridge top 3 planting wheat 4 sowing depths is 5cm, ditch bottom 6 planting wheat 4 sowing depths is 5cm, ridge top 3 and ditch bottom 6 planting wheat 4 seed height differences are 10cm.

[0048]The cultivation method requires small water seepage to p...

Embodiment 3

[0060] In the autumn of 2018, an evaluation and verification test of farmland water and nitrogen supply capacity was carried out in Yueyang Professional Cooperative, Mazhuang Town, Tai'an City: the cultivation method was the same as in Example 1.

[0061] The tested variety: Taimai 18 (big spike variety), sowed on October 7, 2018, with a sowing rate of 12 kg / mu. On October 20, the basic seedlings surveyed were 208,700 plants / mu. Overwintering, harvested on June 7, 2019. During the experiment, the water content (Table 5) and nitrogen (Table 6) of the soil before and after irrigation at the jointing stage of the wheat in the experimental field were investigated. The invention changes the traditional flat furrows into wide and narrow ridges, and the corresponding irrigation method also needs to be changed from flood irrigation with small water seepage to promote the combination of water and soil. After measuring the soil water content at the jointing stage, it can be seen that be...

Abstract

The invention discloses a cultivation method for increasing the interception amount of optical energy of wheat. According to the cultivation method, wheat seeds are sowed in soil at different heightsduring sowing, and a spatial difference is formed between upper and lower rows of the seeds, so that the superficial area of a farmland is increased, staggered layers are formed on canopies of the wheat, the interception amount of light is remarkably increased based on the same variety of the seeds and the maintenance of the labor intensity, conversion of the optical energy to chemical energy is promoted, the utilization rate of the optical energy and yield of the wheat are increased, and the contradiction of insufficient farmlands is relieved. The method disclosed by the invention is simple and does not require extra operations and complex cultivation.

Description

technical field [0001] The invention relates to the technical field of wheat planting, in particular to a cultivation method for increasing the light energy interception of wheat. Background technique [0002] Sunlight is the driving force of wheat photosynthesis, the amount of interception is the key to the level of wheat yield, and the amount of dry matter synthesized by photosynthesis per unit group of wheat during the wheat growth period determines the level of its yield. Therefore, the yield of wheat mainly depends on the rationality of the population, that is, the size, composition, distribution and dynamic changes of the population. The so-called reasonable group structure means that the leaves with the most light and function in the group can obtain sufficient light energy, which is also the key to cultivation. [0003] Most of the traditional wheat planting is to plant the wheat in a flat border, and the growth of the wheat is basically the same. In recent years, ...
