Ask the teachers for help, how to mix nutrient soil with cuttings

The first method.

Here are some guidelines for making fertilizer for your home:

Food waste composting is the process of using microorganisms and small insects in nature to break down organic matter (food waste) in the presence of air and water. The final product is called food waste fertilizer, which is rich in easy-to-use phytonutrients that form part of a healthy soil. It is recommended to buy a bucket and wooden box for composting food waste.

It is best made on the balcony or outdoors. When the food waste compost is fermented, it will have a taste (mainly ammonia and hydrogen sulfide).

Kitchen waste composting mainly has the following conditions: carbon-containing organic matter such as dried leaves, wood chips, paper, peanut shells, melon seed shells, etc. Nitrogen-containing organic matter such as fruit and vegetable waste, coffee grounds, malt powder, etc.

1. Air 2. Appropriate amount of water 3. Treat kitchen waste and turn waste into treasure.

Easy 6 Steps:

1. Separate edible kitchen waste (vegetable peels, fruit peels, a small amount of wasted cooked food) into containers.

2. Collect the dried organic matter (dried leaves, sawdust) in a small container.

3. Take a box or a bucket and drill 4 5 different holes around the container to let air in.

4. Spread a layer of soil on the bottom.

5. Now start adding food waste alternately wet waste (vegetable and fruit skins) and dry waste (straw, sawdust, dry leaves).

6. Cover this container with plastic sheeting or wooden planks to help retain moisture and heat. Some advice Every few days, use a rake to turn the pile quickly to provide inflation. If you feel that the pile is too dry, sprinkle it with some water and make it moist.

Within 2-3 months, your food waste should start to form compost on dry, dark brown soil. There are also ready-made, kitted tools for food waste composting. With time and a little patience, you might enjoy composting food waste.

It is not recommended to use leftover meat, bones, leftovers, leftovers, etc. from food waste.

By sorting, ** and composting, a family of four can reduce waste by 1,000 kg to less than 100 kg per year. Imagine that 90% of all the garbage in Chennai disappeared overnight, a clean green city – and it will help you start your composting journey.

How to use organic fertilizer to prepare nutrient soil:

The ratio of field soil to organic fertilizer is (8:2) (6:4), and the bulk density of the prepared nutrient soil is about 1g cm.

Add a part of peaty soil in the field soil, and then add a certain amount of organic fertilizer, the ratio is field soil: peat: organic fertilizer = 6:3:1, the nutrient soil is relatively loose, the bulk density is about, and the water absorption, heat absorption, and fertilizer retention performance are good.

Do not use vegetable field soil, use grass charcoal and vermiculite, so as to avoid the use of vegetable garden soil may carry the fungus to harm the seedlings, and spread to other vegetable fields, the ratio of grass peat, vermiculite can be 5:5, add organic fertilizer or inorganic fertilizer. This kind of nutrient soil is more loose, the bulk density is about about, and the properties of water absorption, heat absorption, fertilizer retention, and aeration are better.

Vegetable garden soil is the main component of the preparation of culture soil, which should generally account for 30-50%. However, the garden soil can cause infectious diseases, such as cataplexy, blight, early blight and cotton blight of the Solanaceae family, and blight and anthracnose of melons. Therefore, when choosing garden soil, generally do not use the soil of the same family of vegetable plots, and it is better to plant beans, onions and garlic vegetables in the soil.

When choosing other garden soils, be sure to remove the topsoil and dig out the core soil. Garden soil is best excavated in August at high temperatures, after full roasting, crushed, sifted, sieved garden soil should be stored indoors or covered with film, keep dry for later use. Pollution-free seedling raising requires that it cannot be modulated with vegetable garden soil, but with field soil.

02 Organic fertilizer is used according to different conditions in different places, which can be pig manure, garbage, river mud, manure, plant ash, human manure, etc., and its content should account for 20-30% of the culture soil. All organic fertilizers must be fully decomposed before they can be used.

03 Carbonized chaff or plant ash Its content can account for 20-30% of the culture soil. The charring of chaff should be moderate, and generally the chaff should be completely burned through, but the original shape should be basically maintained. Human and animal manure and urine are generally poured in the garden soil to allow the soil to absorb.

It can also be poured on human and animal manure when garden soil, garbage, fence manure, etc. are piled up and fermented together. Superphosphate, which accounts for 2-3% of the total weight of the nutrient soil, should be added to the nutrient soil to increase the content of calcium and phosphorus. Nutrient soil formula At present, the proportion of nutrient soil commonly used in production is:

Seeding bed Vegetable garden soil: organic fertilizer: bran ash = 5:

1-2∶4-3;Vegetable garden soil: river pond mud: organic fertilizer:

Bran ash = 4 2 3 1; Vegetable garden soil: cinder: organic fertilizer = 1 1 1.

Transplant seedbed (nutrient bowl) vegetable garden soil: organic fertilizer: bran ash = 5 2-3 3-2; Vegetable garden soil:

Garbage: chaff ash = 6 3 1 (plus imported compound fertilizer, superphosphate each; Vegetable garden soil: pig and cow dung:

chaff ash = 4 5 1; Vegetable garden soil: cow and horse manure: rice husk = 1 1 1 (cucumber, pepper).

Decomposed peat: vegetable garden soil = 1 1 (Brussels sprouts); Decomposed organic compost: vegetable garden soil = 4 1 (cabbage, nightshade); Vegetable garden soil:

Sand: compost of decomposed bark = 5 3 2. When preparing the nutrient soil for fruit and vegetable seedlings, it is best to add superphosphate leaching solution.

The selection of the above raw materials should strive to be made from local materials, with low cost and good effect.

04 When preparation, stir all the ingredients well and disinfect the nutrient soil with chemicals. About 15 days before sowing, turn over the nutrient mound, adjust the soil pH after sieve, if it is too acidic, it can be adjusted with lime; If it is too alkaline, it can be neutralized with dilute hydrochloric acid. If the soil is too loose, cow dung or clay can be added; The soil is too clay or has very low organic matter content (when it is insufficient, it should be mixed with organic compost, sawdust, etc., and then spread in the seedbed or packed in a nutrient bowl.

Flower cuttings for seedlings should choose a substrate that adapts to plant physiology. For those flowers and trees that are not suitable for cuttings in the soil, the following substrate cuttings should be selected:

River sand River sand is preferably coarse stone that does not contain organic matter, which has the characteristics of good aeration, easy heat absorption, fast heating, and conducive to rooting. However, it has poor water retention and should be replenished in time. This kind of river sand should be cuttings native to tropical desert plants, such as succulent plants in the cactus, epiphyllum and so on, in addition, it is also a good material for leaf cuttings flower millennial orchid, large rock paulownia, the test proves that the river sand and the same amount of peat with strong water retention power mixed materials, for most flower cuttings have a better effect.

Water is suitable for plants that take root by cuttings in water, such as roses, oleanders, pomegranates, etc. The water used for cuttings should be changed frequently to keep the oxygen in the water sufficient, and the container should be a dark bottle to facilitate rooting.

Vermiculite and perlite.

Vermiculite and perlite have recently been recognized as the most desirable substrates for cuttings of various flower seedlings.

peat and humus, etc.

Peat, humus has strong water retention, and if mixed with river sand, it is suitable for cuttings of many temperature flowers. In addition, well-rotted sawdust, humus soil, charcoal soil, etc. can also be used as a substrate for cuttings.

Each cuttings substrate should be disinfected before use, and in addition to the general disinfection method, potassium permanganate solution can also be used to spray the bed or basin surface.

Cuttings pothos, choose the right substrate, and don't even need to change the soil when growing.

In the process of raising early seedlings of potted flower plants, the preparation method of nutrient soil is as follows: 1. For general flower plants: humus soil, garden soil, river reform sand = 3:

5:22, for woody flowers and plants: humus, garden soil, river sand = 4:

5:13, for sowing and propagating seedling soil: humus soil, garden soil, river sand = 5:

3:24, For the advent of flowers and plants: humus.

1.Take a single leaf or a small section of branches and leaves, if possible, you can use rooting powder, soak the branches in ABT6 10 (soluble in water, do not 1 5, 1 5 is soluble in alcohol) rooting powder content of 500 200 mg kg solution for 30 seconds before cuttings.

2.With nutrient soil, the standard mix is peat, perlite and river sand according to 3:1:

The ratio of 1 is mixed and formulated into a substrate, if there is no peat soil, you can use garden soil, no perlite can use sawdust, or you can do without! Perlite is still more expensive! There is no river sand, you can use sand!

The principle of the picture is breathable, moisturizing and fertilizer! The proportions are roughly fine!

3.Cuttings and placed on the north side! Moisturize and you're done! Just touch the soil with your hands every day to moisten it! When dry, you need to water.

4.Temperature! Just take cuttings in a few days! It will be alive in about 2 weeks!

5.It can be potted after rooting! According to the configuration of the culture soil, add some fertilizer! You can use compound fertilizer and twist it into powder! (About 15 to 20 capsules!) ）

In the future management, we must insist on preferring dry and wet by mistake, and pouring that is, pouring thoroughly! That is, the soil should not be too wet, and the watering should be thoroughly watered once! Just leave water from the bottom of the pot!

Experts will tell you how to mix the seedling substrate.

1) Raw material vegetable garden soil (or garbage soil, ditch soil, loam, stove foot soil) 20% 30%, sawdust (or fermented livestock manure, plant ash.

Bran, etc.) 80% 70%.

After sifting the soil of the wet pine vegetable garden with a 6-mesh sieve, remove large soil clods, stones, leaves and other debris, and expose it to the sun. Sawdust should be stacked and fermented until the color turns black before being mixed into the soil for use.

When mixing and raising soil, because the soil has a certain viscosity, the water can not be sprayed directly on the soil, but should be sprayed on sawdust or plant ash before mixing in the soil. (2) Before entering the pool, the disinfected soil is put into the pool after being exposed to sunlight, sterilization and insect repellent. (3) Calcium supplementation is used to supplement turtle insects.

The calcium consumed during spawning and molting promotes its rapid growth and increases spawning, and a certain proportion of calcium can be added to the soil. At present, hydrated lime is mainly added.

The appropriate ratio is 100 (soil) 2 (lime), mixed into the soil and mixed well.
