Planting techniques of turnip

Kohlrabi is popular with people for its high yield and good quality. But it is not easy to grow high-quality kohlrabi. Often high yield, poor quality, hard-hearted, can not eat. So how can we grow kohlrabi well? We should master the following points: the field where kohlrabi is planted should have deep soil layer, convenient irrigation and drainage, fertile soil and sandy loam. Kohlrabi can be directly planted or raised, and the main method is raising seedlings. The sowing period is from late August to mid-September. You can choose the varieties of kohlrabi in Wenling, with the amount of seeds per mu150g and seedlings of 25-50g.

When raising seedlings, carefully prepare the seedbed first, and sow 250 ~ 400g in one mu of seedbed, and 10 ~ 15 mu of field can be planted. After sowing, cover with straw or sunshade net, and pull it out after emergence. Sow once every 65,438+00 days after emergence, with a spacing of 6 ~ 8 cm, and topdressing once. In order to prevent aphids and virus diseases in seedlings, the pure liquid 1500 times was sprayed every 7 ~ 10 days from the first leaf at seedling stage. When raising seedlings, the soil in the seedbed should always be moist to prevent it from being too dry, so as not to affect the growth of roots. After planting 10 ~ 15 days, topdressing 750 ~ 1000 kg of decomposed dilute human excrement and urine, and topdressing again after 10 days. From late October of 10 to early October of 1 165438 10, the fleshy roots of kohlrabi enter a vigorous growth period, and heavy fertilizer should be applied once, and decomposed human manure 1500 kg or urea/mu should be applied. Before fertilization, intertillage and loosen the soil, and fertilize between rows. After 2 days of fertilization in dry weather, water should be poured once to promote the dissolution of fertilizer for root absorption. Clear ditch and cultivate soil 1 ~ 2 times in the growth period, which will not expose the roots and turn green, rough and old-fashioned, affecting the quality. Control Pieris rapae, aphids, Spodoptera litura and other pests. Remove yellow leaves at any time to facilitate ventilation and light transmission. It can be harvested one after another from June 5438 to February, and the harvesting standard is that the stems and leaves of the plants turn yellow, the roots turn from green to yellow, and the leaflets between the leaves shrink and turn yellow.
