Lycium barbarum like cool climate, cold tolerance is very strong. When the temperature stabilizes through about 7 ℃, the seeds can sprout, seedlings can resist -3 ℃ low temperature. Spring temperatures above 6 ℃, spring buds begin to sprout. Wolfberry overwintering at -25℃ without frost damage. Lycium barbarum root system is developed, drought resistance is strong, in the arid desert land can still grow. Production for high yield, still need to ensure water supply, especially the flowering and fruiting period must have sufficient water. Long-term waterlogged low-lying areas of wolfberry growth is unfavorable, and even cause root rot or death.
Sufficient light, wolfberry branches grow strong, flowers and fruits, large fruit, high yield, good quality. Lycium barbarum grows in alkaline soil and sandy loam, most suitable for cultivation in deep soil, fertile loam.
Beet grows well on deep and organic matter-rich loose soil; application of chemical fertilizer and manure are good.
Irrigated, tolerates soils with high saline content, but is sensitive to strongly acidic soils and low boron. Boron deficiency inhibits growth and causes black heart disease in the roots. Sugar beets are widely grown in temperate and cold temperate regions, and in cooler seasons in warmer regions. In the right climate, the growing season is 8 to 10 weeks for vegetable beets and up to 30 weeks for some forage beets.
The first year of growth is mainly nutritive growth, which can be divided into seedlings, leaf clusters, tuberous sugar growth and sugar accumulation in four periods. The second year of growth is mainly reproductive growth, which can be divided into 4 periods of leaf tufts, shoots, flowering and seed formation. Sugar beet is a temperature-loving crop, but cold hardy. The whole reproductive period requires a base temperature of 10 ℃ above the cumulative temperature of 2800 ~ 3200 ℃. The suitable average temperature of tuberous root fertility is above 19℃. When the temperature of the soil 5 to 10 centimeters deep reaches 15 ℃ or more, the tuberous root grows fastest, and nearly stops growing at 4 ℃ or less.
