Hybrid millet double-furrow film-mulching hole sowing cultivation technology

Abstract

The invention discloses a hybrid millet double-furrow film-mulching hole sowing cultivation technology. The cultivation technology mainly comprises the steps: 1, soil preparation and fertilization are conducted, specifically, stubble land which is reserved in the last year is deeply plowed, 900-1000 kg of a base fertilizer is applied per mu before plowing, and 30-40 kg of a nitrogen-phosphorus-potassium compound fertilizer is applied per mu; (2) the sowing time is from mid-to-late April to early May, the sowing rate is 0.25-0.3 kg / mu, the sowing depth is 3-4 cm, and coated seeds and a mulching film with the width of 120 cm and the thickness of 0.005 mm are selected; (3) a double-furrow film-mulching hole sowing machine is selected, two rows are sowed on each film (ridge), hole sowing is performed on 6000-8000 holes per mu on each row, and the seedling number is reduced to 10000-12000 plants per mu; (4) field management is conducted; (5) harvesting is conducted. The problem that the yield and quality of hybrid millet are affected due to immaturity of the hybrid millet cultivation technology in the southern mountainous area of Ningxia is solved, according to the double-furrow film-mulching hole sowing cultivation technology, the inter-seedling density is reduced, the soil moisture is maintained, and the seedling protection rate is improved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation methods, in particular to a hybrid millet double-furrow film-covered hole-sowing cultivation technique. Background technique [0002] Zhangzagu series are new hybrid millet varieties selected by the Millet Research Institute of Zhangjiakou Academy of Agricultural Sciences, Hebei Province through the light (temperature) sensitive two-line method. This variety maintains the high-yield characteristics of the previous hybrid millet, and has the tiller self-regulation ability that most millet varieties do not have. It can automatically adjust the number of tillers according to soil moisture and nutrient conditions. It has high yield with high rainfall and stable yield with less rain, and is more suitable for film-mulched hole planting. efficient cultivation mode. In the process of demonstration and popularization in recent years, this variety has excellent rice quality, stable yield, and is s...

Problems solved by technology

However, during the process of popularization, it was found that the existing four-row film-mulching cultivation mode and three-row film-mulching cultivation technology are not suitable for the climate characteristics of the southern mountainous areas of Ningxia, and the number of seedlings per mu is too large (about 20,000 plants / mu), and the number of holes per mu is too large That is, the number of holes per mu is more than 12,000 holes / mu, and the grouting is not enough in the late growth period, and the thousand-grain weight decreases, which seriously affects the yield and quality of Zhangzagu
