Turnip is a vegetable similar to radish in shape, which is often used to pickle sauerkraut, to make fodder and to be used as food in high and cold mountain areas. In the minds of people in Xinjiang, turnip is a kind of good food for nourishing, protecting the lungs and strengthening the body, which is rich in certain nutrients. Let's take a look at the planting time and management points of turnips.

1. Planting time of turnips

From August to September is the most suitable time to sow turnips and raise seedlings, that is to say, it can be planted at the turn of summer and autumn every year. Varieties can choose Wenling kohlrabi, with the seed amount of direct seeding 150 grams per mu, raising seedlings 2550 grams.

II. Key points of turnip planting management

1. Soil requirements

The fields where turnips are planted should have a deep soil layer, convenient drainage and irrigation, fertile soil and sandy loam. Kohlrabi can be direct seeded or raised seedlings, generally mainly to raise seedlings.

2. Key points of raising seedlings

When raising seedlings, first make a fine seedbed, one mu of seedbed sowing 250kg 400g, can be used for 1015mu field planting. Cover straw or sunshade net after sowing and remove after emergence. The seedlings were planted once about 10 days after emergence, the distance between seedlings was 6-8 cm, and dilute manure was applied once. In order to prevent seedling aphids and virus diseases, 1500 times of liquid was sprayed every 7-10 days from the first leaf of the seedling stage. During the seedling period, the seedbed soil is often kept moist to prevent it from being too dry, so as not to affect the root growth.

3. Transplanting

Ploughing 30 cm after harvest in the field, 3000 kg per mu of rotten-ripe rice fertilizer, 30 kg of superphosphate, 15 kg of potassium chloride or 30 kg of ternary compound fertilizer as base fertilizer. The width of the border is 1.3 to 1.5 meters. The seedling age is about 35 days and should not be too long. When transplanting, the row spacing is 35 cm square, and about 5000 plants are planted per mu. When planting, pay attention to burying the straight root of the seedling in the hole, first put in some fine mud, lift the seedling up slightly, make the root straight, so as not to affect the root elongation, hypertrophy, and then slightly compact and water thoroughly. In case of drought, watering once a day, after 5-6 days, the seedling survives and resumes growth.

4. Key points of management

At 10-15 days after planting, 750-1000 kg of rotten rare human feces were applied and applied again 10 days later. From late October to early November, the fleshy root of kohlrabi entered the vigorous growth period, and heavy fertilizer should be applied once, using 1500 kg of mature human feces and urine or 15 kg of urea and 20 kg of ternary compound fertilizer per mu. Two days after fertilization in dry weather, water was watered once to promote the dissolution of fertilizer for root absorption. During the growth period, clear the ditch to cultivate the soil for 1 or 2 times, so as not to expose the roots to turn green, thick and old, and affect the quality. Control pests such as cabbage, aphids, Spodoptera litura and so on. Remove the yellow leaves at any time to facilitate ventilation and light. It can be harvested one after another in December. According to the harvest standard, the stem and leaf of the plant are withered and yellow, the root head changes from green to yellow, and the leaflets curl and turn yellow between the axils of the leaves. After frosting, the quality of kohlrabi was improved, but it was harvested too late, the hard core was big, the fleshy root fiber was developed, and the processing quality decreased.
