Problems solved by technology

During Zhang Zagu's breeding process, due to the influence of climate factors, the hybridization rate is low, and the problem is that the emergence rate is low
In addition, the annual hybridization rate of Zhang Zagu is not fixed and fluctuates greatly. It is difficult for users to determine a reasonable broadcasting rate when planting.
The planting requirements of Zhang Zagu are also significantly different from those of non-hybrid varieties. Due to the characteristics of strong tillering and high tillering ability of Zhang Zagu, the requirements for seedling density are relatively low. If non-hybrid planting methods are used to guide Zhang Zagu Valley, there will be problems of lodging and production reduction

Embodiment 1

[0017] The selected hybrid seed is Zhangzagu No. 5, purchased from Hebei Xuntian Agricultural Technology Co., Ltd. The test was carried out in Datian, He Village, Lingjingdian Township, Yangqu County, Shanxi Province in 2014, with a test area of ​​300m 2 . Before the test, the hybridization rate (that is, the germination rate) of the hybrids purchased from Zhangzagu 5 was 49%. Weigh 1kg of Zhangzagu No. 5, and then 0.63kg of Jingu No. 29, and mix the two as test seeds. The hybridization rate after mixing is 30%.

[0018] A semi-covered hole planter is used for film-covered seeding, with one hole planting 2 rows each time. The distance between the duck beaks of the planter is 16cm, and the seed amount of each duck beak is 15±3. The average row spacing in the experiment was 50cm, and the number of holes planted per mu was 8300. The test sowing seed dosage is 176g, and the sowing rate per mu is 392g.

[0019] After sowing and emergence of seedlings, two treatments, thinning and fr...

Embodiment 2

[0023] The selected hybrid seed is also Zhangzagu No. 5, purchased from Hebei Xuntian Agricultural Technology Co., Ltd. The experiment was conducted in He Village, Lingjingdian Township, Yangqu County, Shanxi Province in 2015. The farmland of 4 farmers was selected for demonstration of hybrid millet free thinning, and each farmer’s planting area was more than 1 mu.

[0024] The sowing method is the same as in Example 1, except that the mixed seeds are fried Jingu No. 29. According to the investigation, the highest number of seedling holes in the 4 farmland was 7154 holes / mu, and the lowest was 4880 holes / mu; the highest number of seedlings was 23,000 seedlings / mu, and the lowest was 10,200 seedlings / mu. There is a big difference between the number of seedling holes and the number of seedlings in different plots, mainly related to the quality of farmland preparation. The number of seedling holes and seedling emergence in farms with good quality of land preparation is large, and th...

Abstract

A hybridization millet thinning-free plantation method is low in labor intensity and small in output fluctuation; the method comprises the following steps: selecting a Zhuang hybridization millet breed with strong tillering and ear bearing ability according to breed characteristics; carrying out germination tests for the selected Zhuang hybridization millet breed, and determining the germination capacity or hybridization rate of the Zhuang hybridization millet seeds; blending non-hybridization millet with the selected Zhuang hybridization millet seeds according to the real determined Zhuang hybridization millet seed germination capacity, wherein the grain sizes are basically same, thus enabling the blended seeds to have the hybridization rate of 30%; using the half-covering on-film hole spawning mode to plant the blended seeds; spraying herbicide to remove the non-hybridization millet when the millet grows to 3leaf-5leaf after seedling emergence, thus providing weeding effect.

Description

Technical field [0001] The invention relates to a method for planting hybrid millet without thinning, in particular to a planting method of hybrid millet mulching and hole seeding, which belongs to the field of agricultural planting. Background technique [0002] Millet is drought-tolerant and barren, has strong adversity resistance, and has wide adaptability. It is a traditional characteristic planting crop in my country, and it is also the main dryland planting crop. In recent years, Zhangjiakou Academy of Agricultural Sciences has bred a series of Zhang Miscellaneous Millet. Compared with non-hybrid millet, both stable and high-yield performance have been greatly improved. There is already a considerable planting area in my country. Zhangzagu is a small-grain crop like non-hybrid millet, with a thousand-grain weight of only about 3.0 grams. There are also difficulties in seedling preservation and thinning in production. In order to protect the seedlings, the method of increas...
