Planting method and sowing date of red cabbage moss
From late July to late August, 50- 100g seeds were used per mu, 50% carbendazim was used for seed dressing and disinfection, and the seedbed soil was disinfected with quicklime.
Transplant time
From the end of August to the end of September
1. Use quicklime per mu of whole soil150kg;
4-5 parts of 50% soil bactericidal pesticide per mu.
mustard
Pack or 10% easy to spill 2 packs;
13. Use 4 packs of pentachloronitrobenzene per mu (especially effective in preventing and controlling clubroot).
Planting density: 3000 plants per mu, 1 plant/year.
Fertilize soil or land
1. Soil miscellaneous fertilizer 2000-4000 kg/mu (as base fertilizer);
Organic compound fertilizer for vegetables 100kg/ mu (as base fertilizer);
3. 3,000-4,000 kg/mu of human and animal manure: topdressing after surviving cultivation, mainly human and animal manure, about 40 tons per mu. The main moss can be harvested around the National Day, and it needs topdressing once after harvesting, and topdressing once after harvesting.
2. Urea 20 kg/mu;
5. Foliage fertilizer: apply a bag of life source per mu or collect 65,438+0 bags in large quantities or use a phytochemical and spray 30 kilograms of water.
Note: Carbamide is not recommended for vegetables. Fertilizer and water are closely related to the formation of Chinese flowering cabbage. Sufficient fertilizer and water are needed before and after germination to ensure the formation of well-nourished flower stems, especially early-maturing varieties. Nitrogen is the most absorbed mineral nutrient, followed by potassium and phosphorus. The ratio of nitrogen, phosphorus and potassium is 5:3: 1. Flowering stems are long-day plants, but most varieties are not strict about the length of light. The flower bud differentiation and stem growth rate are mainly affected by temperature, and the top flower grows for 50-58 days.
Diseases and pests of red cabbage moss planting
Downy mildew symptom
Restricted by the veins, there are nearly round polygonal lesions on the leaves, and white mold on the back vegetable quilt when wet, and the lesions die in the later stage and turn brown until the leaves are dry.
Drugs:
A. spray150g of 72% frost solution with 600-750 times of water per mu;
B, leijin Domil 100g mixed with water 1000 times spray;
C, 100g poisonous mold spray water for 800 times;
D, frostbite, thiophanate, carbendazim, etc.
soft rot
The main diseases are at the base, which are soaked in water at the initial stage, wet and rotten at the later stage, black and smelly, spread by rain and soaked from the wound.
Drugs:
A,100000 agricultural streptomycin 3000 times, as far as possible with water spray on the basis of multi-purpose liquid medicine;
B, adding 500g of Dixon and 500kg of water to wash the roots;
C, 77% kocide 500 times water spray.
Bacterial angular spot
The lesion on the front of the leaf is brown, and the lesion on the back is polygonal due to vein restriction. The initial stage of the disease is waterlogging, and finally the lesion center tissue dries up and falls off.
Medication: same as soft rot.
Rod-shaped hardened root
The infected leaves become pale and drooping from the seedling stage, especially around noon on sunny days. The roots of diseased plants are swollen and tumor-like, each plant can reach about 2 0%. In the later stage, the diseased site was infected by soft rot fungi, which led to tissue decay and the whole plant died.
Drugs:
A, mainly use 150kg quicklime to disinfect the whole soil during seedling raising and transplanting.
B, when transplanting, use 1.5kg-2kg pentachloronitrobenzene mixed with base fertilizer per mu for application, or use 4-5 packages of soil bactericidal pesticides.
C, apply more decomposed organic fertilizers, such as compost, furnace ash pig manure, fireclay ash, organic compound fertilizer, etc.
control of insect
Main pests: Plutella xylostella, Pieris rapae and aphids.
Drugs:
A. Treatment of Pieris rapae and Plutella xylostella: kill all kinds of insects, suppress criminals, kill them, destroy them and be killed by the enemy;
B, treatment of aphids: afudin, echinocyanin, Emily, Lesburn.
pay attention to
It is forbidden to apply organophosphorus pesticides such as methamidophos, phorate, parathion and methyl parathion, and high toxic and high residue pesticides such as dimethoate and omethoate on vegetables. Carefully use sensitive pesticides such as triadimefon, chlorpyrifos, fenvalerate, cypermethrin, cyhalothrin and chlorothalonil on vegetables, reduce the frequency of using vegetables every season, and strictly ensure the safety interval. For other pesticides, fungicides and insecticides, it is also necessary to ensure a safe interval (that is, the number of days from the last application to the harvest).
The story of red cabbage moss There are many legends about red cabbage moss. One saying is: According to legend, more than 700 years ago, in a small village at the foot of Hongshan, there was an eighteen-year-old girl named Yu Ye, who was beautiful and ingenious. There is a young man named Tian Yong in the next village. He is diligent, simple and helpful. The two admired each other and fell in love for a long time. In the spring of March, they went to visit the beautiful Hongshan, which is called? Too old? Yang Xiong's cauliflower touched it. Yang Xiong saw that Jade Leaf was beautiful, so he let Bing Yong take her away. Tian Yong fought hard and rescued Yu Ye, pulling her to run down the hill. When Yang Xiong saw the gains and losses of beautiful girls, he told Bing Yong to shoot them with an arrow. Suddenly, the blood of Tian Yong and Yu Ye stained the land under their feet. Yang Xiong saw human life and rode away. Suddenly, a flash of lightning killed Yang Xiong and his friends on the mountainside. Later, the locals buried Tian Yong and Yu Ye where they died. Later, the graves were covered with purple little Xin Wei, and the villagers often watered and fertilized them. In autumn, the local area suffered a big pest disaster, and the crops were not harvested. The villagers picked purple moss stalks around the grave to eat, and they felt sweet, crisp and fragrant, and more and more of them survived the famine. After autumn, every family collects rapeseed and grows it in their own gardens. When they are free, they pick cabbages and sell them in the city. The city people are full of praise for eating this rare vegetable, and the reputation of red cabbage moss is getting bigger and bigger, and more and more people are planting it.
