Okra planting conditions

Moisture is resistant to drought and moisture, but not tolerant. When the soil moisture in the germination period is too large, it is easy to induce seedling blight. The result is drought, the plant grows poorly, and the quality is inferior. The soil should always be kept moist.

Light okra is particularly sensitive to light conditions, prefers strong light, requires long light hours, and sufficient light. Should choose the sunny block, strengthen ventilation and ventilation, pay attention to reasonable close planting, so as not to shade each other, affecting ventilation and light transmission.

Soil nutrients Okra has a wide adaptability to the soil and can not be grounded. Saline-alkali land can also be planted, but it is more suitable for loam or sandy loam with deep, loose and fertile soil and good drainage. Fertilizers are mainly nitrogen in the early stage of growth, and more phosphorus and potassium fertilizers are needed in the middle and late stages.

Okra has a lot of value, and his efficacy is very high. The market value is also very high. However, in the okra planting process, special attention should be paid to the prevention and control of pests and diseases.

Aliphatic Polycarbonates APC

A polymer whose molecular backbone contains aliphatic esters. In other words, the parent nucleus R of the dihydroxyl compound HO -- R -- OH is polycarbonate of aliphatic group (CH2) M, (CH2)O(CH2), -- CH2 -- C(CH3)2 -- CH2 -- etc. It is characterized by low melting temperature, mostly below 60℃, and narrow melting range, greater solubility, low mechanical strength, hydrophilic, poor thermal stability, low glass transition temperature. Most aliphatic polycarbonate have low molecular weight and are mostly viscous liquid at room temperature or microcrystalline substance at low melting temperature. It can be prepared from aliphatic dihydroxyl compounds with dicarbonate or photogasification. Most of them have little industrial value, so their application is very limited.
