Problems solved by technology

[0007] Aiming at the current wheat production, due to intensive sowing and unscientific soil preparation, etc., which lead to fierce competition among wheat individuals, the wheat populations in the Huanghuaihai region generally have low emergence uniformity, poor population quality, weak seedlings, low tillering efficiency, and low yield. Problem, the present invention combines the nutrient and water competition problem in the wheat growth process, provides a kind of Huang Huai Hai winter wheat single-grain uniform sowing cultivation method in a targeted manner, and this cultivation method carries out seedbed finishing to create good seedbed when sowing winter wheat After the conditions are met, the wheat single-grain leveling machine (W-2019D407) is used for sowing, and the winter wheat single-grain precision sowing is carried out according to the requirements of agronomic indicators such as accurate plant spacing, row spacing, sowing depth and sowing rate, and the same depth of covering soil and deep base fertilizer are achieved. target

Embodiment 1

[0041] This example was carried out in the experimental field of Jingzhi Town, Anqiu City, Weifang, Shandong Province in 2019-2020, and the area of ​​the experimental field was 1400 mu. The tested wheat variety was Jimai 22 (bred by the Crop Research Institute of Shandong Academy of Agricultural Sciences). Before sowing, on October 5, 2019, one deep plowing and two rotary plowing were carried out on the plot. The depth of deep plowing was 23 cm. At the same time, plowing was carried out to make the ground level, and then one irrigation was carried out. Before wheat sowing, 1% Shenzimycin was used for seed dressing treatment, and on October 08, 2019, it was sown with a wheat single-grain leveling machine (W-2019D407), such as figure 2 As shown, the wheat row spacing is 5 cm, the plant spacing is 3 cm, the sowing depth is 3 cm, and the sowing rate is 17.5 kg / mu. The wheat in this example was harvested on June 18, 2020.

Embodiment 2

[0049] This example was implemented in Zhouzhuang Village, Jiaomiao Town, Qihe County, Dezhou City, Shandong Province in 2019-2020. The soil of this plot is loamy soil, and the wheat variety planted is Jimai 44, a high-quality special wheat. Before wheat sowing, one deep plowing and two rotary plowing were carried out on the plot, with a deep plowing depth of 25 cm, and plowing and moisture creation were carried out. Before sowing, the wheat was seed-dressed with 1% Shenzimycin, and the wheat was sown on October 10, 2019 with a wheat single-grain leveling machine (W-2019D407). The wheat row spacing was 5 cm, the plant spacing was 3 cm, and the seeding rate was 16.8 kg / mu, sowing depth of 3 cm. The wheat in this example was harvested on June 22, 2020.

Abstract

The invention belongs to the technical field of wheat planting, and particularly relates to a Huang-Huai-Hai winter wheat single-grain uniform sowing cultivation method. The cultivation method comprises a seedbed finishing step and a precision seeding step; and when winter wheat is sown, seedbed finishing is carried out to create good seedbed conditions, then a seeder carries out winter wheat single-grain precision seeding according to agricultural index requirements of accurate row spacing, line spacing, seeding depth, seeding quantity and the like, and the purposes of the consistent earthingdepth, deep application of base fertilizer and the like are achieved together. According to the cultivation method, resources such as light, heat, water and fertilizer can be utilized to the maximumextent, mechanical sowing management of the winter wheat in a Huang-Huai-Hai region is integrated through accurate optimization of plant spacing, the row spacing, the seeding depth and the like duringsowing, and the purposes of good crop group construction and yield increase and efficiency increase are achieved.

Description

technical field [0001] The invention belongs to the technical field of wheat planting, and in particular relates to a single-grain even-sowing cultivation method for Huanghuaihai winter wheat. Background technique [0002] Wheat is the third largest grain crop in my country after rice and corn. The perennial planting area accounts for about 22% of the total grain area, and the total output accounts for about 21% of the total grain output. It is of great significance to maintaining national food security and social stability. The natural ecological conditions of the Huanghuai winter wheat region are the most suitable regions for wheat growth in China. The wheat area and total output of the Huanghuai winter wheat region account for about 45% and 48% of the national wheat field area and total output, respectively. For a long time, there have been problems in wheat production in this area, such as multiple and chaotic planting methods, large sowing volume, poor sowing quality, a...
