What is good for interplanting spring wheat? Intercropping crops varieties and techniques

Intercropping spring wheat with cotton is better, because the barrier function of wheat can directly affect the invasion of cotton aphid. This intercropping method is very beneficial to cotton aphid at seedling stage, and it can be controlled generally without pesticide application. It should be noted that spring wheat should be interplanted with fine varieties and sown in time. For example, in northern Hebei and northwestern Shanxi, spring wheat should generally be sown around March 15.

The seedling survival rate of spring wheat interplanting Bupleurum chinense increased by17.6%; The biomass of Bupleurum chinense increased by 25.5%, which improved the quality and yield of Bupleurum chinense. Its economic benefit is far greater than harvesting more spring wheat.

What is the high yield of spring wheat intercropping? The yield of spring wheat interplanting with edible sunflower is relatively high, and efficient cultivation requires careful soil preparation and reasonable fertilization. Select excellent wheat varieties, timely sow density and strengthen management; Implement scientific management to promote plant growth; Harvest in time to ensure the appearance quality of seeds.

Intercropping spring wheat with cotton is the best crop. Because of the barrier effect of wheat, it can directly affect the invasion of cotton aphid. This intercropping method is very beneficial to cotton aphid at seedling stage, and it can be controlled generally without pesticide application.

What is the best benefit of spring wheat interplanting? Wheat intercropping with soybean, soybean rhizobia can fix nitrogen in the air, and wheat root exudates contain a lot of carbohydrates, which provide nutrients to each other, thus achieving the effect of increasing production and income.

Technical method of spring wheat interplanting 1, sowing: spring wheat interplanting alfalfa generally adopts ridge planting method, spring wheat is sown in large ridges, and alfalfa is sown flat. Alfalfa is known as the king of pasture, which not only has high yield, but also has excellent grass quality.

2. Field management: The planting area of alfalfa is constantly expanding, and the primary roots of alfalfa can go deep into the ground. When the plant grows for more than 20 years, if the subsoil is porous, the depth of the taproot can reach more than 15 meters (50 feet), so alfalfa has strong drought resistance. The roots of seedlings can penetrate 90 cm into the soil at 2 months and reach 180 cm (6 feet) at 5 months.

Matters needing attention in spring wheat interplanting: Spring wheat interplanting should choose excellent varieties and sow in time. For example, in northern Hebei and northwestern Shanxi, spring wheat should be sown around March 15, while corn should be sown around April 20, when the ground temperature of 5cm has stabilized at 10. Two plants in a hole can make the density reach 400 plants/mu.
