How to control the row spacing and plant spacing of cabbage planting? How many seedlings do you need

After the main meal, pour pea water once, fertilize the rosette machine and water together, and apply 20 kg of Wudang. Top dressing during balling can be carried out with organic and compound fertilizers, after which they are watered once a week depending on the weather. When cabbage enters the most vigorous growth period, the third top dressing is implemented, and the Wudang element is 25 kg.

Cabbage planted in plastic greenhouses in early spring is prone to black rich disease, soft rot and so on. Black rot and soft rot are bacterial diseases that can be prevented by spraying wet powder, white fungus pain wet powder, agricultural streptomycin, etc. on cotton.

In terms of pests and diseases, the main mites and bean worms that harm the cabbage in plastic greenhouses are mites and bean green worms, mites can hang yellow boards on plastic greenhouses for physical trapping, do a good job of insect repellent work in plastic greenhouses, and lay insect repellent nets in the windproof area to prevent insects from entering the greenhouse. Vegetable greenworms can alternately use Xi'an urea emulsifiable concentrate, phenyl ester emulsifiable concentrate, fine flushing melting oil and other agents to achieve insecticidal effect.

When planting seeds, be careful not to negotiate with qualified enterprises or seed companies to produce seeds that become a problem. Select the parents used as propagating seeds, and select varieties with strong affinity, wide adaptability, good anti-epidemic and disease resistance, and in line with the characteristics of specific varieties according to the breeding goals. In the Huanghuai area, the seedlings are generally sown before and after the Bailu Festival in the summer at the seedling raising time, and it is decided to sow the female parent 7 10 days ago, and then sow the male parent.

The seedbed is high, well ventilated, easy to prevent waterlogging and irrigation, and it is better not to plant plots of winter melon and vegetables. Make meters wide, depending on the situation. Nutrient soil formula, soil and completely spoiled farmhouse manure in a ratio of 633604.

1 kg of special compound fertilizer for seedbed per cubic meter, 8 10 grams of carbendazim, 100 grams of neo-yellow phosphorus granules are fully mixed, fully mixed into a sieve, and 3/4 of the water is tamped. Evenly sow the seeds, spread the remaining nutrient soil, about 1 cm thick, spread the mulch, insert the arch, cover the shade net, and when the seedlings are more than 70% unearthed, remove the mulch film in time to prevent the seedlings from being burned. Bonsai should be carried out in the 4-5 leaf period, it is best to be bonsai on cloudy days, bonsai is best, it should be poured out secretly and illuminated.

Seedling pest control, seedling main, insect control, weeding, drought and flood harvest work, timely weeding, this period of pests mainly include cabbage worms, cabbage moths, aphids, in recent years, the number of powdery mildew has increased dramatically, the greater the harm, to prevent in time. Prevention** Mainly use thiamine, thuringiensis, avermectin mite 10%, yellow phosphorus, etc., and use it in turn according to the instructions. Generally, 7-8 leaves of cabbage in autumn, officially eaten in mid-October, before transplanting, plots with convenient drainage, before transplanting, the remains of the whole crop are completely removed, and the quicklime powder is sprinkled on the ground, flat and deep rake.

Warehouse, high-temperature disinfection, sterilization and insecticide, planting row spacing meters, stump stubs and mother books should be separated from sowing to seedling, regular, and harvesting, and cannot be mixed.

The row spacing of cabbage is generally 50 to 55, the plant spacing is 35 to 40, and there are about 5,000 plants per acre.

Generally, according to the soil fertility planting, the soil fertility is slightly worse suitable for high-density cultivation, generally the row spacing is 40 cm, the plant spacing is 30 cm, about 5500 plants per mu.

However, as far as basal fertilizer is concerned, cabbage generally needs to be combined with land preparation to apply 3 000-5 000 kg of fully decomposed farm fertilizer, 30-35 kg of superphosphate or 25 kg of compound fertilizer per mu, etc., which can be applied deeply, sprinkled or striped.

Each acre of land should be about 2,500 kg to 3,000 kg, which is very suitable. In this way, you will get a very good planting.

It mainly depends on the growth of cabbage, and it is probably necessary to apply kilograms, but when applying farmhouse fertilizer, it is necessary to mix water.

It's about 2,700 kilograms, and in this way, the fertility of the land is guaranteed, and chemical and organic fertilizers can be mixed together.

In fact, it is quite appropriate to apply kilograms of farm fertilizer, which can only be used after dilution.

<> cabbage is generally determined by the row spacing and plant spacing, taking the row spacing of 55 cm and the plant spacing of 35-40 cm as an example, 3000-3500 plants can be planted per mu. When planting cabbage, you can choose seedlings with a seedling age of about 40 days, or a strong seedling that has grown 6-8 true leaves, and then plant in the evening on a cloudy or sunny day, according to the above row spacing and plant spacing, generally 3000-3500 plants can be planted per mu.

First of all, the soil must be very fertile, and these plants prefer some shady and cold places, so you can put it in a cool and shady place. It is best to sow in late September. In this way, the quality of the kale can be improved.

1. Select varieties, choose early-maturing varieties with a short growth period, a single ball weighs about 1 kg, and is about 45 days after planting to the harvest period, which is more suitable for consumers' consumption habits, and does not affect the sowing period of the next stubble overwintering vegetables, such as Dutch varieties Switzerland. 2. Sowing seeds in a timely manner, cabbage seedlings do not have strict requirements for temperature, but the requirements for temperature at the balling stage are very strict, which should be about 17, which is conducive to the formation and growth of leaf balls. Therefore, the summer sowing time is around late July.

When planting, the soil needs to be very moist, and the surrounding environment is relatively warm, in this case, you can grow very good cabbage, and you should also choose a good soil and choose a good planting location.

To plant in a well-ventilated area, the soil in the place must be fertile, watered enough so that there is no grass on the ground, and fertilizer must be put in the ground.

First of all, when planting, you must choose the land with relatively fertile and wide soil, and in the process of fertilization, you must choose farmhouse fertilizer, and do not use fertilizer bought outside. And also to water more, to prevent the occurrence of pests and diseases, if there are small bugs, then be sure to spray insecticides.

Hello dear! How many trees (plants) are planted per mu of cabbage is generally determined by the row spacing and plant spacing, taking the row spacing of 55 cm and the plant spacing of 35-40 cm as an example, 3000-3500 plants can be planted per mu. When planting cabbage, you can choose seedlings with a seedling age of about 40 days, or a strong seedling that has grown 6-8 true leaves, and then plant early in the evening on a cloudy or sunny day, according to the above-mentioned row spacing and plant spacing, 3000-3500 plants can be planted per mu.

How many days does cabbage seedling rearing have the highest transplanting yield? What is the best day for planting?

Hello, glad for your question. The transplanting yield of cabbage seedlings was the highest after 45 days. At 45 is the most suitable Cong Zhao brother should be planted.

The transplanting time of different varieties of cabbage will vary, taking summer cabbage infiltration as an example, it generally takes about 45 days from sowing to transplanting. Cabbage prefers a mild and cool climate, it has a certain cold tolerance and clumps, and its growth temperature range is wide, and it can grow and bulb normally in an environment with an average daily temperature of 6-25.
