Soil, mulching is important for Chinese potatoes

When you think of China, do you think of potatoes? It may not be, but in the Loess Plateau area in the northwest of China, potatoes are the main food.

Although crops are so important, the potato product is lower than they can. The area has a dry climate with unnecessary need. Common droughts, especially springtime when the crops are just emerging. If the humidity of the earth was more reliable, the potato potato would be better.

Rong Li and colleagues at the University of Ningxia in Yinchuan, China, discovered how different habits and mulching could improve new humidity – and crop yield – in the Loess Plateau The researchers investigated three craft options (normal, no-return, and sub-section) together with three mulching options (no mulch, straw mulch, and plastic film).

Usually, the Loess Plateau enclosures are plowed, made, after harvesting and left bare to spring. This is called traditional tillage. Conservation excavation may not fill the soil between crops (no return). Another conservation option has been removed: to break the soil deeply with a long blade, without turning it. A whirlwind helps water; entering the soil and its water storage development in the soil.

Li said, "We did not know if a trick with mixed roofing practices would improve illness during the rate of seeding and potatoes in those dry farming areas."

The team examined the same range over two years – a very dry year after a wet year. For each combination of new administrative options, they measured surface temperatures, water content of the soil, the level of flowering, and the market yield of potato catheters.

A plastic roof that was warming up the soil was larger than the other mulching options. Straw mulch had a cooling effect compared to a plant. However, all three options make nuts temperatures in the right range for early breeding; potatoes. So, surface temperature would not seem to be the main reason for the early flourishing.

Instead, the team decided that illness was the main factor that was a barrier limit. The wetter of the soil during the time of compilation is essential for crop success. Practices that maintained the surface of the ground were better at both lower levels; better and peacefully established. Both are essential for the creation of ducks and market produce.

Other results include:

  • It's growing seeds. lower with current and roofless tillage compared to other treatments.
  • The highest yields came when they were applied with a plastic mulch.
  • Within the same option, seams in a roof plock were much higher than those without mulching.
  • It's the result of a product Top tallest potatoes with roofed holes, and then there was a plastic roof.
  • Conservation tillage (both back-to-under and subsoiling) with roofed tow was brought to higher potato fruit and market tubes rates compared to other treatments.
  • The highest yield of potato tissue was found in the highest market; combustion of a roof with a towstone. This product was 14.9% higher compared to current roofless roof.

Li and his team decided if their main objective is to & # 39; Increase the utility of the earth, a roof ax should be selected. Nose is also relatively low and environmentally friendly, and a plastic roof can cause pollution problems and is a more sustainable way.

"We recommend conservation woodlands along with arable roof like farm use more favorable for tough opponents in potato crops," said Li. "This combination has a great potential for greater crop production in our area and similar continental farming sectors of the world."

In the Loess Plateau, where the potatoes are a king, these products may be truly royal.
