Problems solved by technology

80% of the soil where corn is planted in Wuling mountainous area is dry land with medium and low yield, most of which are dry sloping land with poor soil, without irrigation conditions, and are vulnerable to drought; the input for corn production is less, the amount of fertilizer is insufficient, and nitrogen fertilizer is applied in preference, and phosphorus and potassium fertilizers are seriously insufficient , fertilization and cultivation techniques are not matched, and the utilization rate of fertilizers is low, which limits the development of corn production; the planting area of ​​new drought-resistant and barren-resistant good corn varieties suitable for planting in barren soil accounts for a small proportion of the sown area; extensive management is suitable for selection of late maturity For large spike varieties, the habitual planting density is 2500-2800 plants / mu, and the density is low, which is not conducive to high yield.

Embodiment Construction

[0019] A method for cultivating spring corn in mountainous areas, the steps are as follows:

[0020] 1. Select varieties: Select drought-resistant, barren-resistant, high-efficiency, high-yield, high-yield, grain-forage varieties that have been approved or introduced for demonstration, and are suitable for local planting. Medium and large spike type is the main type. The results of experiments and demonstrations show that the varieties suitable for large-scale planting in Wuling Mountains are Nongda 108, Linao 1, Xiangyu 10, Lianyu 15, Sanbei 2, Denghai 11, Dongdan 60, and Yongke 5. No. 1 or Beiyu No. 1 or Sanbei No. 6 or Denghai No. 9 or United No. 3 or Great Wall 218 or Denghai 3632 or Chengyu No. 15 or Zunyu No. 8 or Qingyu No. 4 or Ziyu No. 3 or Aoyu No. 17 Or more than 20 varieties such as Zhongke No. 8. These varieties are planted in Wuling Mountains, and the yield per mu can reach about 500 kilograms.

[0021] 2. Timely sowing: Sowing can be done when the ground temp...

Abstract

The invention discloses a method for cultivating spring corn in hilly region wherein breeds, seeding date, density, mulch film blanketing and mulch film nursery sock grow transplanting, fertilizer application are considered for increasing maize production, experimental investigation and demonstration application are conducted to spread the fine breeds suitable for the Wuling Mountains which have the advantages of late ripening, medium late ripening, big ear, medium-sized to large ear.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation. More specifically, it relates to a high-yield cultivation method for spring corn in mountainous areas. The technology is suitable for corn production and technology promotion in departments such as farmers, seed companies, agricultural research and teaching, and agricultural technology promotion. Background technique [0002] Corn is an important grain and feed crop with high yield, commonly known as "the king of high yield" and "the king of feed". China is a major corn producer in the world and one of the three golden corn belts in the world. Its corn production is second only to the United States, ranking second in the world. Corn accounts for about 1 / 4 of China's grain production. In the main producing areas, corn is the main source of farmers' income, and the corn economy has become one of the leading factors in regional economic development. Corn is not ...
