Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a kind of broomcorn sowing and cultivation technology before winter, which solves the problem that in the prior art, the sowing of broomcorn millet is carried out in spring, when sowing in spring is dry and rainless, and most of the planting areas are severely lacking in water resources and cannot be irrigated Replenishing water, although broomcorn millet has a strong ability to tolerate drought, but when there is less rain in the early stage, it will seriously affect the absorption and utilization of soil nutrients, which will lead to a decrease in the emergence rate of broomcorn millet

Embodiment 1

[0057] When preparing for sowing, first select the land: choose flat land with deep soil layer, fertile soil, strong water and fertilizer retention capacity, and good drainage and ventilation. For the first stubble, choose wheat stubble that does not use high-residue pesticides, corn stubble, and potato stubble with good farming conditions to avoid repeated stubble and direct stubble; then land preparation: Ningxia’s arid and semi-arid area has abundant rainfall in autumn and winter, and spring is dry and less rainy. The moisture mainly comes from the moisture at the end of the previous year, so it is necessary to use it in autumn, winter and spring, and storing moisture is the key measure to preserve the seedlings of broomcorn millet. After the autumn crops are harvested, deep plowing should be carried out in time. The depth of the plowed land should be above 20cm. After rotary plowing, harrowing should be carried out to ensure that the ground is flat and free of litter, which...

Embodiment 2

[0059] When selecting varieties and treating seeds, first select varieties: select high-yield, high-quality, and strong-resistant broomcorn varieties suitable for spring sowing areas; then seed treatment: one week before sowing, spread the seeds on the field on a sunny day with a thickness of about 2cm-3cm, Turning in the sun for 1-2 days, the sun-dried millet can increase the germination rate and germination potential, the seed purity and clarity are above 98%, the germination rate is greater than 85%, and the water content is below 14%. Before sowing, use 40% isofenphos-methyl EC or phoxim EC and 70% imidacloprid WP to dress the seeds according to 0.3% of the seed amount, and then sow after drying.

Embodiment 3

[0061] When sowing, sowing time: start sowing when the ground temperature is stable below 10°C in winter, and the film-covered sowing is completed at one time. The general sowing time in the arid and semi-arid area of ​​​​Ningxia is around late October to early November; then mulching with plastic film: choose the film width 1300mm, 0.10mm thick plastic film with strong tensile strength, the dosage per mu is 3.5 kg to 4.5 kg. The film covering method is to lay the film flat, keep the film surface flat, close to the ground, compact the film head and the film sides on both sides, without showing the edge, and the film distance is 40cm to 50cm. Cover the film evenly with fine soil with a thickness of about 1 cm to ensure that the film will not be punctured and lifted by wind and sand. 35-50 cm. The sowing rate per mu is 0.25-0.30 kg, 8-10 grains are sown in a single hole, and the number of holes per mu is about 8000-10000.

Abstract

The invention discloses a technology for sowing and cultivating broom corn millet before winter. The technology includes the steps of preparing before sowing, selecting land, selecting flat land which is deep in soil layer, fertile in soil texture, strong in water and fertilizer retention capability and good in drainage and ventilation, selecting wheat stubble without using high-residual pesticide and corn stubble and potato stubble which are good in cultivation condition as previous stubbles, and avoiding continuous cropping and alternate cropping; selecting varieties and treating seeds; sowing the seeds; conducting field management; controlling diseases, pests and birds; and in the jointing and booting stage of the broom corn millet, spraying 40-50 kg / mu of a 0.2%-0.3% monopotassium phosphate aqueous solution on leaf surfaces of plants in sunny days, and the situation that the broom corn millet can absorb and utilize the solution as soon as possible is guaranteed. According to the technology for sowing and cultivating the broom corn millet before winter, the major problems that sowing in spring is dry and less in rain, the emergence rate is low, late-maturing varieties cannot be mature and the like can be effectively solved, meanwhile, the yield and quality of the broom corn millet can be improved, diversified development of the broom corn millet is enhanced, and the income of farmers is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of sowing and cultivation, in particular to a pre-winter sowing and cultivation technology of broomcorn millet. Background technique [0002] Millet has a short growth period and drought tolerance. It is the main cultivated crop in Ningxia. The planting area is 500,000-600,000 mu. Millet has high nutritional value and balanced nutrition. It is no longer used as a simple food crop, but as an economic crop. 80 More than 100% of the grains are sold and exchanged as commodities. Mino grass is fed to cattle and sheep. It has high feed value and is a high-quality forage grass. It has become one of the main sources for local farmers to increase their income and enterprises to increase efficiency. With the rapid development of diversification of broomcorn millet industry, people's requirements for its demand and quality are also increasing. Although the existing spring sowing rain harvesting cultivation technology h...
