The white radish is very popular with foodies, how to grow white radish?1, the whole land fertilization to choose pollution-free plots, in the application of sufficient basal fertilizer on the basis of the broken stubble, autumn deep turning 30
cm. stubble replanting plots of the whole land should be carried out in the previous crop harvested immediately after the stubble and weeds, the application of high-quality farmyard fertilizer 45 t/ha, mixed into the diammonium phosphate or composite fertilizer 300 ~ 450 < / p>
kg/ha to do the bottom of the ridge, the ridge width of 55 ~ 60 cm, the ridge height of 25 cm. 450
kg/ha as a bottom fertilizer to start the ridge, the width of the ridge is 55~60 cm, the height of the ridge is 25 cm.
For the prevention of underground pests, 50% phoxim emulsifiable concentrate 52.5 L/ha is mixed into a poisonous soil, with the base fertilizer is applied to the ridge and furrow (prohibited the use of high toxicity and high residue pesticides). The organic fertilizer applied must be fully rotted, otherwise it is easy to injure the main root, forming a gibberellic acid root and affecting the yield. Fly maggots are the main pests for the growth of radish, have a tendency to rotten organic habits, production should be noted.
2, sowing seed sowing time for June 25 to July 5th. High ridge spot sowing or planing dibble sitting water seed, sowing amount of 00~75
kg/ha; plant spacing of 23 cm, keep seedlings 7.0~75,000 plants/ha. 4~5 seeds per hole, seed spread in the hole, mulch 2
cm, so that the seed and soil in close contact, to prevent drought to "bud dry" and waterlogging to "smothering" phenomenon, to ensure that the seedling full, seedling strong.
3, field management
1) between seedlings. Seedling should not be too early, because the fleshy roots are formed by the hypocotyl elongation, appropriate late seedling is conducive to the hypocotyl elongation, seedling can be divided into two times to complete, the first time in the 3 true leaves time seedling, each hole to stay 2 plants, the second in the 5 true leaves when the seedling, each hole to stay 1 strong seedling.
2) Plowing. Plowing loosens the soil, promotes the growth and development of the root system, and makes the main root deep. Requirements for deep hoeing grooves, shallow hoeing the back of the ridge. Wet hoeing deep, dry hoeing shallow, shallow at the beginning, deep in the middle, do not hurt the main root.
3) water and fertilizer management. Into the belly period, water control squatting seedlings, fleshy root expansion period of watering, to maintain the field water holding capacity of about 60%, base fertilizer is insufficient, combined with the watering of fertilizer, urea and potassium sulfate 150 ~ 225 kg / ha, from the seedling 10 cm away from the eye of the eye into the spray can also be 0.5% potassium dihydrogen phosphate and other foliar fertilizers, the effect of increased yields is obvious.
4, pest control
Priority to the use of integrated agricultural control technology, biological control and physical control of a combination of scientific and rational application of chemical control methods to minimize the use of pesticides and residues, the production of pollution-free products in line with national standards.
Agricultural control. Select disease-resistant varieties or use integrated cultivation measures to prevent disease and reduce the use of pesticides; implement crop rotation, remove diseased plant residues in the field, deep tilling to reduce the base of pests and diseases; apply net fertilizer, organic fertilizer must be fully rotted, and irrigate with clean water.
Physical control. Set up insect nets, the use of black light to trap adult insects, the use of silver gray film to avoid aphids, good seed disinfection treatment can prevent viral diseases.
Biological control. Protect the natural enemies, create environmental conditions conducive to the survival of natural enemies, the use of biological agents that do not harm the natural enemies or pesticides with low lethality, such as imidacloprid, abamectin, bacillus thuringiensis and other pesticides.
Pharmaceutical control. Promote the use of high-efficiency, low-toxicity, low-residue pesticides, prohibit the use of highly toxic, high-residue pesticides. The use of pharmaceuticals, in strict accordance with the safety standards promulgated by the state, to ensure the production of pollution-free agricultural products.
Harvesting and processing white radish grows to its maximum when the yield is the highest, the quality is also the best. Harvesting generally begins in early September. Before processing, the top of the radish will be peeled to the root of the leaf, washed with water, and change the water diligently, in order to process the white radish strips. Processing tools are generally self-designed, "five knives" processed into 1
cm square strip; "a knife" processed into a triangle strip, into 4 large pieces, the thicker radish processed into 6 ~ 8 pieces, triangle strip is not easy to be too fine, and strictly according to the requirements of the process. Processed radish hanging in a ventilated place to dry, preferably in the field 1 row rows, divided into upper, middle and lower 3 layers, courtyard drying to build a high shelf, radish and ground distance of not less than 1.2
m, sun to 9% dry can be off the shelves, the length of the separate bundles into a 0.5 kg/bundle, solid, the requirements of the bundle shape is neat, and placed in a ventilated place drying to be sold.
