Early season usually cabbage or mushy rot caused by bacteria, want to limit the disease for tree growers to make good all the stitching.

Choose and processed the same

Early season, cabbage is not favorable development was not a priority because of the weather. Therefore, growers should select varieties with tolerance to heat as Takii (T40); KK Cross, Phong Thuy, Roma or purple cabbage Sakata.

Buy the new SX or similar bags in shelf. Seeds should be sown before being treated with warm water (boil 2 3 cold) for 20 minutes or treated with fungicides. Then cold water soak 8-10 hours and then sow.

It's best to sow the seeds in Styrofoam boxes or seed trays elected to ensure all rising, seedlings are not lost due to the hot sun or heavy rain. Appropriate amount of particles is 2 gr / m2.

Choose and farmland prices

Prices may in trays or foam boxes include 40% land, 30% husk item, 30% manure or compost microbial lime + 0.1% or 0.01% describe Trichodecma fungal antagonists (Biobus). Seeds in a greenhouse nursery, home screen or cover up when heavy rain, hot sun.

If the weather alternating sun and rain should extend preventive died in the seedlings watered by Biobus preparations have preventive effects for plants to stimulate root development.

Also need to add 1-2 times the preparation of high fertilizer helps plants healthy leaf and a qualifying contract.

The soil is best cabbage slight loam, or sandy alluvial soil with a neutral pH of 5.5 - 6 Service to need sooner or rain raised bed and narrower than the other (wide beds 0, 8-1 m, high 25-30 cm wide trench 30-35 cm), up to the bed in the form tortoiseshell good drainage. The soil of early cabbage should not do too well and hit the bed tightly.

Early season usually cabbage or mushy rot caused by bacteria, want to limit the disease for tree growers to make good all the stitching.

For the best arable land should be treated with anti-fungal preparations Trichodecma by mixing into a pit of manure amounts as recommended by the manufacturer. Without opposition, the fungus can use lime or copper fungicide to describe soil treatment before planting.

Planting and care

Early crop should not be planted too vulnerable offspring eyed, dead trees are best to have 6-7 true leaves before subculture.

Appropriate planting density of 50 x 35-40 cm. The soil should be applied before planting lined with item number 400 kg of compost or organic micro replace (40 kg) + 6-8 kg NPK 16: 16: 8 + 0.8 to 1 kg super micro.

This service should not be a pit of manure application, so vulnerable to losses due to runoff or evaporation. Nitrogen and potassium used for top dressing fertilizer 3 times (at tree roots, spread eagle and began rolling tobacco) can draw water when the sun or shade mix fertilizer buried 10 cm stem from the rain or sun hot.

To improve the quality of later cabbage and increase resistance to disease, adverse weather resistant, in addition to providing original fertilizer, farmers need additional fertilizer because of high plant leaves especially corn era book follow the recommended dosage on the package.

Digging, watering

Cabbage rains of early or make the bed thrust should turn to digging and earth, plants 2-3 times / season favorable to plant growth. Absolutely not plow seedbed when raining or too wet fields will ease as dead trees rot caused by invading bacteria and fungi.

The large cabbage leaves should be watered regularly so that moisture seedbed moisture always reach 75-80% (intact soil blocks while holding on and no water leaked out).

If prolonged rain should have a positive impact measures such as widening ditches, dredging momentum, digging holes for water lapping the field corner fast, super phosphate fertilizer or fertilizer to plant roots super fast recovery .

Period rolling corn plants if encountered unfavorable weather to supplement a super potassium fertilizer + foliar micronutrient spray periodically for vegetables 1 time / week to help book more favorable for corn.

Plant Protection

Objects such as aphids black, deep blue, silk worms and mushy rot bacteria often arise and harm of early cabbage.

Farmers need to practice integrated pest management, seed health seriously, crop rotation, intercropping plants, fertilizer balance, reasonably new irrigation to minimize the hazards caused by the disease.

  Use chemicals when necessary according to the true principles 4, pay attention to the biological drug to ensure safe vegetables.

* Note:

- Do not fertilize too late or urea fertilizer for cabbage abuse will reduce the quality of trees, many pests and harmful to the health of users. If in case there is more rain to reduce nitrogen fertilizer, and increase potassium and micronutrients for vegetables.

- Should intercropped with tomato or garlic cabbage silk worms to limit damage.

- If prolonged rain to irrigate antagonistic fungi in the roots of 1-week regular / limited time to shake the tree dies.
