Corn wide and narrow row planting technology notes

Posted on

Corn wide and narrow row cultivation technology is applied to large and medium-sized agricultural machinery operations, ridges are changed to flat, uniform ridges are changed to wide and narrow rows, three shovels and three rakes are changed to one deep loose, and the next year rotation is planted alternately and alternately. The wide and narrow rows of corn were cultivated by changing the current ridge (60-65 cm) to a width of 80 cm and a narrow row of 40 cm. The prominent characteristics of wide and narrow rows of corn cultivation techniques are that the ridges and ridges are sideways, the trees and trees are the tops, and have good ventilation and photosynthesis, and are suitable for high density plants. There are several issues to be aware of in production applications:
1, pay attention to select the dense varieties, to increase the density when sowing.
2, the combination of base fertilizer, mouth fat and topdressing fertilizer, deep application of base fertilizer, combined with deep pine for top dressing before jointing in corn.
3, using mechanized precision (encryption) sowing.
4. If severe drought occurs in mid-growth period, it is not suitable to perform deep loosening operation. At this time, deep loosening will aggravate drought; deep loosening period should be appropriately delayed.
5. It is not appropriate to use this planting mode because it is unfavorable for raising the temperature.

Precious Metal

Rhodium powder Rh≥99.95% Properties: silver-white metal, extremely hard, wear-resistant, also has considerable ductility Application: It can be used as raw material for electrical instrumentation, chemical industry and manufacture of precision alloys. Rhodium powder is based on the widespread use of ruthenium in the industrial industry. Since rhodium is a rare metal required by the industry, the industry price is slightly higher than that of general non-ferrous metals. Rhodium, one of the rare elements, has various uses. Rhodium can be used to make hydrogenation catalysts, thermocouples, platinum-rhodium alloys, etc. It is also often plated on searchlights and reflectors, and is also used as a polishing agent for gemstones. and electrical contact parts.
