Key points of cultivation technology:1The suitable sowing period is October 10 25, and the basic seedlings are 150,000-200,000 seedlings per mu. 2.Pay attention to the prevention and control of stripe rust, powdery mildew, sheath blight, and scab.

Approval opinion: This variety meets the national wheat variety approval standards and has passed the approval. It is suitable for early and middle stubble planting in Henan Province (except Nanyang and Xinyang), northern Anhui Province, northern Jiangsu Province and Guanzhong area of Shaanxi Province in the southern part of Huanghuai Winter Wheat Area.

1. It is not suitable for late sowing.

2. It is not suitable for sowing in low-seeded fertile fields.

3. Bainong Dwarf Resistance to Huai Rot 58 is an epoch-making new wheat variety bred by the Wheat Breeding Center of Henan University of Science and Technology and developed and operated in 2003. This variety is a semi-winter medium-ripening variety. The seedlings are creeping, the leaves are light green in winter, there are many tillers, frost resistance is strong, the growth is stable in spring, and the tillers are strong and the stalks are strong.

The plant height is about 70cm, high lodging resistance, and good fullness. The three elements of yield are coordinated, with about 450,000 ears per mu, 38 40 grains per ear, and 42 45g per 1000 grains. High resistance to powdery mildew, stripe rust, leaf blight, hidden grinding lesions, medium resistance to sheath blight, strong root vitality, good maturity and yellowing.

Generally, the yield per mu is 500 550kg, and the maximum yield can reach 700kg.

Bainong Dwarf Kang 58 is a high-yield and multi-resistant wheat variety bred by Professor Jianchun Ru Zhengang of Henan Institute of Science and Technology, which is the wheat variety with the largest planting area in the southern Huanghuai wheat area, the leading wheat variety in China, and a major scientific and technological special variety in Henan Province.

Dwarf Kang 58 is a semi-winter dwarf stalk and multi-spike type variety, which has strong cold resistance, and has no frost damage when sown early at the end of September, so it is suitable for early sowing and dense planting. The results of sowing date test showed that the yield of Bainong Dwarf Kang 58 was sown before October 30, and the yield of Bainong Dwarf Kang 58 was small, and the yield sown on October 10 was the highest. Yields sown after 30 October have declined significantly. From the perspective of high yield, the most suitable sowing date is early to mid-October, and the best sowing date is around October 10.

The height of the dwarf resistance 58 plants was low, which was more suitable for planting in high and medium fertilizer fields. More fertilizer application and proper top dressing are the basis for obtaining high yields.

Dwarf resistance 58 high resistance to stripe rust, stalk rust, powdery mildew manuscript sail resistance. The focus of pest control is aphids, leaf rust and scab. Spray dimethoate or other agents to control aphids before and after heading, and spray powder rust at the filling stage to prevent leaf rust and scab.

<> wheat varieties with higher yields than Dwarf Kang 58 include Triple Antibody Dwarf Youwang, which was officially launched in 2015. Before planting wheat, it is necessary to select seeds with large particles, allocate pesticides according to a certain proportion of pesticides, and then mix the pesticides and wheat with the mixture. Before planting, the land needs to be thinned and sprinkled with fertilizer, and when the wheat is planted, it can be cultivated directly by machine.

1. Higher yield wheat than dwarf resistance 58

1. Wheat with higher yield than Dwarf Kang 58 has three anti-dwarf Youwang and other varieties, which is a wheat variety launched in 2015, which has the characteristics of wide adaptability, strong stress resistance, high yield and stable yield, and has increased the yield by 12-23% compared with Dwarf Kang 58 in terms of yield.

2. Before planting wheat, we must select seeds with large particles, configure them according to the proportion of pesticides, and then modulate the configured pesticides and wheat. The land on which wheat is grown must be flat and easy to drain and irrigate, and wheat should generally be planted in autumn and must not be planted when it is too cold.

3. Before planting wheat, the land should be loosened and sprinkled with fertilizer, and when the wheat is officially planted, it can be directly cultivated with a machine, or manually pit with tools, but it must be planted in a humid environment.

2. Introduction to dwarf resistance 58

1. Dwarf Kang 58 wheat is a semi-winter dwarf stalk and multi-spike variety, and its cold resistance is extremely strong. This variety has solid stalks, short internodes at the base, and strong lodging resistance, so it is suitable for early sowing and dense planting. In terms of production, the yield per mu of this variety is generally 500-600kg when planted in a large area, and the yield per mu of high-yield demonstration fields can exceed 700kg.

2. Dwarf Kang 58 is a high-yield and multi-resistant wheat variety bred by Henan Institute of Science and Technology, which is the wheat variety with the largest planting area in the southern Huanghuai wheat area, and is also the leading wheat variety in China and a major scientific and technological special variety in Henan Province.

3. Bainong dwarf Kang 58 can resist the low temperature of -16 at the seedling stage, and can safely overwinter when planted in the wheat area in the southern Huanghuai region. Its root system is well developed, and the root depth of the tillering stage is increased by 20-30cm compared with that of the control variety, and the drought tolerance is strong.
