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 was Zhang Zagu No. 5, which was 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 (ie germination rate) of the purchased hybrid Zhangzagu No. 5 was 49%. Weigh 1kg of Zhangzagu No. 5, then weigh 0.63kg of Jingu No. 29, and mix the two as seeds for the test. The hybridization rate of the mixed seeds is 30%.

[0018] A half-covered hole planter was used for film-covered seeding, and one hole was planted in two rows each time. The distance between the duckbills of the seeder is 16cm, and the seeding amount of each duckbill is 15±3 grains. The average row spacing in the test was 50cm, and the number of sowing holes per mu was 8300. The amount of seed sown in the test is 176g, and the sowing amount per mu is 392g.

[0019] After sowing and emergence, two ...

Embodiment 2

[0023] The selected hybrid seed is also Zhangzagu No. 5, purchased from Hebei Xuntian Agricultural Technology Co., Ltd. The experiment was carried out in He Village, Lingjingdian Township, Yangqu County, Shanxi Province in 2015. Four farmers were selected for the demonstration of hybrid millet-free thinning. The planting area of ​​each farmer was more than 1 mu.

[0024] The sowing method is as in Example 1, except that the mixed seeds are fried Jingu No. 29. After investigation, the highest number of emergence holes in the four farmlands was 7154 holes / mu, the lowest was 4880 holes / mu; the highest number of seedlings emerged was 23,000 seedlings / mu, and the lowest was 10,200 seedlings / mu. The number of seedling holes and the number of seedlings varies greatly between different plots, mainly due to the quality of the farmland preparation. The number of seedling holes and the number of seedlings in the farmland with good soil preparation quality are more, and the number of seed...

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 planting method of hybrid millet without thinning, in particular to a film-covered hole-planting method of hybrid millet, belonging to the field of agricultural planting. Background technique [0002] Millet is resistant to drought and barrenness, has strong stress resistance and wide adaptability. It is a traditional characteristic crop in my country and a major dryland crop. In recent years, Zhangjiakou Academy of Agricultural Sciences has bred a series of Zhang Zagu. Compared with non-hybrid millet, both stable yield and high yield performance have been greatly improved, and it has a considerable planting area in my country. Like non-hybrid millet, Zhang Zagu is a small-grained crop, with a thousand-grain weight of only about 3.0 grams. There are also problems of difficult seedling preservation and thinning in production. In order to preserve the seedlings, the method of increasing the seeding rate is often used in produc...
