The latest seed price and planting method of cabbage

Cabbage is one of the important vegetables in our country, also known as lotus white, cabbage, cabbage, etc., is an annual or biennial herb of Brassica genus of Cruciferae, its various varieties originate from the Mediterranean Sea to the North Sea coast, cultivated as vegetables or feed in all parts of our country, let's take a look at cabbage seed prices and planting methods together!

How much is a gram of cabbage seeds?

The price of cabbage seeds is about 2~4 yuan a gram, but the price varies greatly due to the quality, variety, origin and market of seeds. Cabbage in the production of seed sowing for reproduction, like warm and humid, sufficient light, cold, but also have the ability to adapt to high temperature, growth temperature of 15~20℃, fleshy stem expansion period such as more than 30℃ high temperature meat is easy to fiber, the selection of soil is not very strict, but suitable for humus-rich clay loam or sandy loam planting.

Method of sowing cabbage

1, variety selection: cabbage planting should choose a short growth period of early-maturing varieties, single ball weight of about 1 kg, planting to harvest period of about 45 days, more suitable for consumer consumption habits, and does not affect the next winter vegetables sowing period, such as Dutch varieties Switzerland, etc.

2, seedbed fertilization: cabbage seedbed soil formula for 6 parts of field soil, 4 parts of decomposed organic fertilizer, each cubic meter of nutrient soil to add 1 kg ternary compound fertilizer, 80 grams of carbendazim, 100 grams of phoxim seed pull agent, mix well to make beds, bed width 1.2 meters, length is not limited.

3, sowing time: cabbage seedlings on the temperature requirements are not strict, but the heading stage on the temperature requirements are very strict, should be around 17℃, conducive to the formation and growth of leaf bulbs, so summer sowing time is about late July.

4. Sowing method: cabbage is planted in late July, and then the prepared seedbed is irrigated with sole water, and then the seeds are evenly sprinkled, covered with fine soil about 1 cm, covered with film to keep moisture, inserted into the arch, and covered with sunshade net.

5. Remove the film and divide the seedlings: When more than 70% of cabbage seedlings are unearthed, remove the film in time to prevent baking and injury of the seedlings. When the seedlings grow to 2 leaves and 1 heart (about 10 days after sowing), divide the seedlings once. Divide the seedlings in the evening or cloudy day is conducive to survival. The water for dividing the seedlings should be poured in the dark ditch and thoroughly.

6. Seedling management: cabbage seedlings have strong resistance, but they must do a good job in pest control and grass prevention. Insects include aphids, diamondback moths and cabbage bugs. Wanling and 1.8% avermectin can be used alternately. Due to the short seedling time, it can be used twice according to the insect situation.

How to grow cabbage

1. Soil preparation and fertilization: It is appropriate to select the beans or melons with non-cruciferous crops before cabbage planting. Apply decomposed organic fertilizer 3000 kg and nitrogen, phosphorus and potassium ternary compound fertilizer 30 kg per mu. Turn the land to make beds with a width of 1.2 meters, plant 2 rows and a plant spacing of 40 cm.

2. Reasonable close planting: cabbage seedling age is about 40 days, 6~8 true leaves are planted in cloudy days or sunny evenings, 3000~3500 plants are planted per mu, about 3500 plants are Meimei No.2 and Baosheng cultivated in autumn, and about 3000 plants are Huyue and Crown in winter.

3. Fertilizer and water management: after cabbage planting, intertill and squat seedlings, reduce fertilizer and water to promote underground growth, keep soil dry and wet after seedling slowing, so as to expand leaf assimilation area, and focus on top dressing in the peak growth period of rosette leaves and heading period.

1. After cabbage seedlings were planted, fertilizer was applied, mixed solution of 0.3% urea and 0.3% potassium dihydrogen phosphate was applied, and intertillage was used to loosen soil and weed control.

(2) Apply topdressing once at the early stage of rosette leaf growth of cabbage, apply urea 10kg per mu, and spray 0.2% borax solution on leaf surface once at the same time.

3. Apply topdressing once in the peak growth period of rosette leaves, and apply ternary compound fertilizer 15kg per mu.

④ cabbage in the early and middle stage of topdressing twice, each mu of ternary compound fertilizer 10kg.

5. In order to prevent dry heartburn, 0.7% calcium chloride can be sprayed 2~3 times in the heading stage.

4. Appropriate harvesting: cabbage leaves can be harvested when they are compact, and 2 outer leaves are reserved during harvesting to protect the leaves, so that the surface is clean, no pests and no cracked balls. At the same time, according to the standard requirements for preservation and processing exports, classification is carried out according to the size of the leaves.

Control of cabbage diseases and insect pests

1. Downy mildew

[Hazard] Downy mildew is an important disease of cabbage, distributed everywhere, endangering leaves, when the disease spots converge, the leaves turn yellow and die.

[Control] 50% thiram wettable powder or 75% chlorothalonil wettable powder with 0.4% seed weight can be used to dress seeds before sowing. After planting, spray 80% mancozeb 600 times solution for prevention.

2. Cataplasia

[Hazard] Common symptoms include dead seedlings and damping-off. Dead seedlings occur before germination after sowing, and damping-off occurs before true leaves unfold after seedling emergence.

[Control] Immediately pull out the diseased seedlings and spray 800 times solution of 25% metalaxyl wettable powder or 500 times solution of 64% oxfrost·manganese zinc wettable powder or 500 times solution of 72.2% propamocarb solution every 7~10 days for 2~3 consecutive times.

3. Sclerotium disease

Sclerotinia sclerotiorum is an important disease of cabbage, which is widely distributed and obviously affects yield and quality. It can harm stem base, leaves, leaf bulbs and seed pods.

[Control] At the early stage of disease, spray 800 times of 50% ammonium chloride wettable powder or 500 times of 40% thiophanate·carbendazim suspension once every 10 days for 2~3 consecutive times, focusing on spraying plant stem base, old leaves and ground.

4. Black root disease

Black root disease is an important disease of cabbage, which is widely distributed and common, and significantly affects the yield and quality of cabbage.

[Prevention and control] Spray 20% chlorothalon-methyl 1000 times solution or 60% do-Fu 500 times solution or 75% chlorothalonil 600 times solution or copper-ammonia mixture 400 times solution at the early stage of disease, once every 7 days, for 2~3 consecutive times.

5. Black spot disease

Black spot disease is a major disease of cabbage, widely distributed, the incidence rate of diseased fields is about 30%, serious up to 100%, significantly affecting yield and quality.

[Prevention and control] Before or at the early stage of disease, 400~500 times solution of 70% Zineb WP or 500~600 times solution of 75% Chlorothalonil WP can be selected, once every 7~10 days, for 2~3 consecutive times.

6. Soft rot

[Hazard] Soft rot occurs everywhere. The affected part is infiltrated and translucent first, then the affected part turns brown, soft rot, subsidence, white pus, sticky feeling to touch, and foul smell.

[Control] At the early stage of disease, spray 72% agricultural streptomycin sulfate soluble powder 3000~4000 times solution, or neophytin 4000 times solution, or 14% ammonia copper solution 350 times solution, spray once every 10 days for control, and continuously control 2~3 times.

7. Black rot

[Hazard] Black rot mainly damages leaves, leaf bulbs or bulbs. The cotyledons are water-stained and then quickly die or spread to the true leaves.

[Prevention and control] In the early stage of disease and during the period of easy disease, timely spray 350 times solution of 14% copper ammonia solution, or 600 times solution of 60% copper succinate·ethyl phosphine aluminum wettable powder, once every 7~10 days, for 2~3 consecutive times.
