Organic potato suitable for planting density analysis
In summer, the growth and development of organic potatoes is in a high temperature and stormy season. Although organic potatoes can still flower and pod at around 35 °C, the environmental conditions are gradually deteriorating, resulting in a decrease in seed set rate and a delay in branching. Here's a look at the specific density of organic potato planting:
The planting density of organic potatoes is usually determined by the leaf area index, and the reasonable leaf area index of potatoes is 3.5-4.0. The leaf area is mainly determined by the planting density. The higher the density, the larger the leaf area index. Conversely, the smaller the density, the smaller the leaf area index.
Under normal circumstances, early maturing varieties are shorter due to shorter plants, and the leaf area is relatively small. Therefore, the early-maturing organic potato varieties should be densely planted; the late-maturing planting plants are tall, the growing season is long, and the planting density is dilute; the fertile land has strong nutrient supply, the plants are tall, the leaf area is relatively large, the planting density is thin, the thin land is poor, and the nutrition is insufficient. Plants are small, the leaf area is small, and the planting density should be large; the irrigation conditions should be thin, and the dry land should be dense. In addition, different planting densities are not the same, commercial potato should be thin when cultivated, seed potato production should be dense; French fries should be used for processing, and starch processing should be dense.
