What are the benefits of the nutrient bowl for seedling raising

The bowl soil should be nutritious. The amount of nutrients in the soil and whether the nutrients are complete not only affect the quality of cotton seedlings, but also affect the growth process after transplanting. It is necessary to choose fertile surface cooked soil without blight, verticillium wilt and no saline-alkali components, start to prepare soil before winter, and apply fertilizer in advance after the beginning of spring, so that the soil can be fully ripened and finely broken.

In order to ensure that the nutrient bowl is rich in nutrients, sufficient organic fertilizer and phosphorus and potassium fertilizer should be applied, and the organic fertilizer should be fully decomposed human and animal manure or manure is the best. Generally, 250 500 kg of sieved manure or 200 400 kg of human and animal manure are applied per mu of bed soil, 15 25 kg of superphosphate and potassium chloride, 25 50 kg of rotting cake fertilizer, organic fertilizer and chemical fertilizer are mixed with the surface cooked soil, and the ratio of fertilizer and soil is 1 4 5. Effectively achieve the combination of organic fertilizer and inorganic fertilizer, fast-acting fertilizer and late-acting fertilizer, and the combination of nitrogen, phosphorus and potassium.

According to research reports, the fertility index of bowl soil is generally above the content of organic matter, above total nitrogen, 100 mg kg of available nitrogen, and more than 30 mg kg of available phosphorus.

Nitrogen fertilizer should be applied and turned shallowly before making the bowl, and the face should not be applied in contact with the seeds, so as not to affect the germination and emergence of cotton, especially urea. Urea is a highly concentrated nitrogen fertilizer. After being applied to the soil, it is decomposed by soil microorganisms to form ammonium carbonate or ammonium bicarbonate, and ammonium carbonate is then hydrolyzed into ammonia and carbonic acid, and ammonia is easy to vaporize and escape, and in the dissolution of urea particles, there is often a strong alkali with a pH of 9 11 and an environment with high ammonia concentration, forming a high ammonia strong alkali area, and the nitrite acid nitrogen content is also increased accordingly.

If the seed enters this area, it will cause root tip necrosis, the taproot can not be stretched down, and the hypocotyl is also difficult to elongate, resulting in cotton seedlings coiling, can not germinate and emerge normally, in view of the majority of cotton farmers often take urea as seedbed base fertilizer application, for this reason, it must be emphasized that urea should not be used as seedbed base fertilizer.

On the first floor, the "nutrition bowl", its abbreviation (flower pot, plastic container), is actually the plastic container flower pot that we commonly use today. It is made of low-density polyethylene; Low density polyethylene Chinese code, ldpe I briefly explained. (Benefits) 1. Adapt to the mature stage of "greenhouse planting", that is, "vegetables, melons and fruits" and "seeds".

His practical nutrient bowl, heat absorption during the day, heat preservation and root protection at night, fertilizer protection, can make these crops, favorable growth, 2, adapt to the "dry season", (is the so-called dry season, is not conducive to the growth of crops), but the nutrient bowl, he can effectively keep warm, is not conducive to the dispersion of water, heat preservation and water retention, and indirectly protects crops. 3. To prevent the damage of "insects" to crops, the general crops (roots, sprouts and seeds) are more or less chewed by insects, but the nutrient bowl effectively prevents this. It has a layer of chemical protection clothing for crops, which is conducive to the breeding and harvesting of vegetable farmers, and greatly improves the planting benefits.

Thus increasing the economic benefits, (values) universal practical nutrition bowl, can be done, (transplanting is convenient), reducing the adverse factors for the natural environment. The number of cheap seeds has decreased, and the sprouts that cannot be absorbed by fertiliser. Generally, our winter (vegetables and fruits) is not conducive to growth due to environmental factors.

But grown in greenhouses. Moreover, the use of nutrient bowls provides convenience for my demand, and it can also be exported to Europe and the United States, opening up the market, and thus increasing the income of farmers

<> nutrient bowl seedlings have been widely used in the seedlings of eggplant fruits and melons, and the seedlings through the nutrient bowl are conducive to cultivating strong seedlings. There are various forms of nutrient bowls, including straw bowls, paper bowls and plastic bowls.

1. Grass bowl: Thin the leaf tips after drying the new straw, cut it into 35-4o cm long, tie it into L in the middle of every 2o or so, and then spread the grass evenly from the middle to the surrounding in a radial shape, press into the ceramic or enamel ware with a diameter of lo-l4 cm, about lo cm high, and smooth inside, so that each straw is evenly dispersed on the inner wall of the vessel, fill the culture soil, compaction in 2 times, fill about half of the first time, and press it tightly to make the bowl firm, and the second time only slightly compacts the edge of the bowl. The soil of the mu should be slightly higher than the mouth of the bowl, and finally the top of the bowl mouth is tied with straw around the perimeter, and the grass bowl is lifted out of the vessel.

The culture soil should be fertile and loose, and the water should be suitable. Although this method is more labor-intensive, it can be used locally and the cost is low. The straw outside the bowl can also absorb water, which can properly alleviate the damage of water accumulation in the roots of seedlings, and the straw also has a fertilizer effect after rotting.

2. Paper bowl: use old newspapers to cut it into 8-l2 sheets, and fold it by hand. Paper bags are generally 8 l2 cm high and 6 lo cm in diameter.

There are various ways to stick, one is to fold the old trapped branch newspaper in half 8, wrap its 3 5 around the lower bottle body of the beer bottle, and then fold the unwrapped part back 3 times according to the bottom of the bottle to form the bottom of the bag, and then gently pull out the bottle. In order to prevent the paper bag from loosening, the bottle should be filled with soil immediately after being pulled out, and the seedlings should be divided into small waters, and small water should be watered, not too much water, otherwise the paper bag will be soaked.

The bottomless paper cylinder method is to make a cylindrical paper bowl mold with iron sheet according to a certain size, with a handle, the culture soil is loaded into the mold, the old newspaper is cut to an appropriate size, and the paper bowl mold is turned over in the yang furrow, and the mold is put forward, and the culture soil is left in the paper bag to form a complete paper bowl.

3. Plastic bowls: Polyvinyl chloride or polyethylene plastics are pressed into high-speed potato lo-l2 cm, upper diameter lo-l3 cm, bottom diameter 8-lo cm, various types of plastic bowls with wide upper and lower narrowness, which can be reused for 3-4 years, which is convenient and labor-saving. Seedlings are raised in plastic bowls, which are easy to raise seedlings when planting, do not hurt the roots, and do not need to slow down the seedlings after planting.

Therefore, the plastic bowl is currently the most commonly used seedling container for vegetable seedlings.

In order to save the cost of seedling raising, you can also cut and sew the discarded old plastic film into a simple plastic bowl, or choose a paper bowl for ice cream, which has a good effect.

4. Seedling tray: It is a seedling appliance used to cultivate 2-3 true leaf seedlings, mostly plastic or wooden, generally 4o cm long, 3o cm wide, and about cm high. There are small drainage holes at the bottom of the tray, and the substrate or culture soil is filled into the tray when used, and the seeds are sown and covered with soil.

The substrate for rapid seedling raising was better with the ratio of l 3 each of carbonized rice husk, garden soil and decomposed organic fertilizer.

The seedling tray is easy to use in home vegetable planting, especially the free furrows and walkways in the greenhouse or greenhouse. If there is no greenhouse and greenhouse, you can build a simple yang furrow in the yard during the day, put the tray in the simple yang furrow, if the temperature is insufficient at night, you can move it to the house, and then move it out on the second day, and the seedlings can be planted in the yang furrow when they grow to 2 to 3 true leaves.

Nutrient bowl seedling rearing induces flower buds by controlling the nitrogen nutrient status of plants in the nutrient bowl. Generally, the flower buds are differentiated in mid-September, and the harvest begins in late November, and the harvest is about 10 days earlier than the seedbed seedlings. In recent years, various production areas have invented and promoted labor-saving measures such as the elevated nutrient bowl seedling method and the three-dimensional trellis five-layer seedling method, as well as a series of seedling methods and supporting technologies such as non-false planting seedlings, net room isolation and pest prevention seedlings, and aerial seedling collection.

Interpretation: A bowl containing more nutrients and used to cultivate crop seedlings. with soil or peat, fertilizer and.

Mixed with water in a certain proportion, it is made by putting it into a bowl-making utensil.

Nutrient bowl (also known as seedling bowl, seedling cup, seedling pot, nutrition cup), its texture is mostly made of plastic, the size of the paper cup is mostly used for breeding, seedlings, and the size of the flower pot is mostly used for greenhouse planting. The black plastic nutrient bowl has the functions of heat absorption during the day, heat preservation and root protection and fertilizer retention at night, and water retention in drought seasons. Breeding and seedling raising with nutrient bowls are convenient for centralized cultivation and transplanting, significantly improve economic benefits, and are widely used in agricultural planting such as flowers, vegetables, melons and fruits. The market is mainly based on the nutritional bowl products of Hebei Tangshan Plastic Products Factory.

The nutrient bowl is a container, so it is called the nutrient bowl because it can be transported with nutrients such as soil, which can improve the survival rate of transplanting and break the seasonal limitation.

Nutrient bowl seedling cultivation is a method of root protection and seedling raising, which is more meaningful for the early cultivation of vegetables such as eggplant fruits and melons, because it has the following advantages:(1) The nutrient bowl uses prepared nutrient soil, which is rich in nutrients and is conducive to cultivating strong seedlings. (2) The nutrient bowl is convenient for enlarging the seedling spacing and avoiding the seedlings from squeezing each other, so as to control the growth of the seedlings and prevent the growth of seedlings.

3) Seedlings can be raised with nutrient bowls to prolong the seedling age, so as to achieve large seedling planting. (4) Nutrient bowl seedlings can play a role in root protection, and the seedlings are slow down after planting.

The nutrient bowl is a relatively simple, relatively low-cost flower pot, and the general material is a thin plastic flower pot, which is good with fiberglass.

Nutrient bowl seedlings are transplanted into flower bowls to raise flower seeds or seedlings. In the past, it was mostly used to cultivate ornamental flowers, put flowers at abnormal times, etc., but now it is also used in urban greening. In order to ensure the survival rate, the seedlings are transplanted into the nutrient bowl after the seedlings are collected in the spring to the seedling field, and then planted at any time when needed.

It is cultivated in a nursery bowl of a certain size.

Pepper seedlings are conducive to protecting the root system of seedlings and are a good root protection

Seedling measures. The plastic nutrient bowl can be used many times, and it can be used to water and sow or divide seedlings when it is used into nutrient soil or substrates such as peat, vermiculite, etc., and placed in the seedling furrow. Watering is done thoroughly.

Nutrient bowl seedlings should pay attention to replenish water, and at the same time water the nutrient solution in time, it is best to move the seedling bowl once in the later stage of seedling raising to prevent the root system from penetrating into the ground. When planting, the seedlings are transported to the cultivation furrow with the bowl, and the seedlings are poured out of the plastic nutrient bowl to be planted.

The seedling raising method of golden-skinned zucchini can be divided into two types, namely nutrient bowl seedling raising and ordinary seedbed seedbed seedling.

Please tell me about the nutrient bowl for seedlings?

At present, many qualified pepper growers use plastic nutrient bowls to raise seedlings. There are roughly two specifications of domestic plastic nutrition bowls, 10 cm, 10 cm, 8 cm and 8 cm, 8 cm and 6 cm. Fill the nutrient bowl with nutrient soil, and water it after the seedlings are divided, so that the nutrient bowl should be watered thoroughly.

Special attention should be paid to the preparation of nutrient soil and water management during the seedling period when using nutrient bowls for seedling raising. The water evaporation of nutrient bowl seedlings is fast, and it should be replenished in time, especially for soilless seedlings, and water management needs to be strengthened. In addition, because the position of the seedlings in the seedbed is different, its light and temperature are also different, which is easy to cause the size of the seedlings, so it is necessary to change the position of the seedlings frequently to avoid the appearance of the large and small seedlings.
