In recent years, dust storms have become more frequent in spring, particularly in North and Northwest China, where spring droughts have been severe and temperatures have risen rapidly. This has made it challenging for newly planted trees to establish strong root systems, leading to lower survival rates. However, autumn planting has proven to be a more effective strategy. During this season, temperatures gradually decrease, evapotranspiration is low, and soil moisture remains stable, allowing plants to recover and grow more efficiently. Trees such as *Pinus tabulaeformis*, *Pinus armandii*, *Phellodendron chinensis*, *Populus tomentosa*, *Astragalus membranaceus*, *Forsythia suspensa*, and many others thrive when planted in the fall.
For example, species like privets and similar varieties have shown excellent results when planted in autumn. The roots of hardy tree species can begin to restore growth under warm soil conditions, and even if the topsoil freezes, the root system can continue to develop as long as the permafrost layer is not too deep. This early root activity helps ensure better survival and growth in the following spring.
Autumn planting not only addresses the challenges of limited planting time and labor shortages during spring but also improves overall survival rates. It is an efficient and practical method for tree planting, especially in regions with harsh winters and dry springs.
**Planting Time:**
Deciduous trees should be planted before the ground freezes. Autumn planting should be done as early as possible. For instance, *Populus tomentosa*, *Scutellaria baicalensis*, and other deciduous trees can achieve 100% survival rates when planted in mid-November. Evergreen conifers like *Pinus tabulaeformis*, *Pinus armandii*, and cypress can be planted from mid-October to mid-November, with similar success rates. Low-growing shrubs such as *Euonymus japonicus*, *Cyclovirobuxium brevifolia*, *Ligustrum quinquefolium*, and *Viola tricolor* can also be planted in late October, achieving a 98% survival rate.
**Tree Specifications:**
The size requirements for autumn planting are similar to those in spring. Evergreen trees are typically 1.5 to 3.5 meters tall, deciduous trees have a trunk diameter of 4 to 20 centimeters, and shrubs range from 0.3 to 2.5 meters in height.
**Planting Techniques:**
Trees are usually dug up and planted based on their size or root ball. The planting depth should be 3 to 5 cm deeper than in spring, and the soil should be compacted after planting. After planting, water should be applied immediately, then again after 3 days and 10 days. After the third watering, the planting hole should be sealed for winter protection. Cold protection measures, such as mulching, should be applied around mid-November. In the following spring, regular watering and maintenance should be carried out.
**Precautions:**
1. Ensure thorough watering after planting.
2. All seedlings, especially small shrubs like boxwood, must be planted deeply, and the planting hole should be tightly packed to prevent cracks and water loss due to strong northwest winds in winter.
3. Dwarf shrubs should be pruned appropriately right after planting to protect them from cold. Avoid short pruning that may reduce their ability to withstand winter frost. Keep branches long enough to avoid damage from cold snaps.
4. Cold-tolerant species are best suited for autumn planting, while less hardy trees, such as magnolias and *Liriodendron*, with fleshy roots, should be planted in spring to avoid transplant shock.
By following these guidelines, autumn planting can significantly improve tree survival and promote healthy growth in the coming seasons.
Distillers Dried Grains With Solubles 26%
1. DDGS Product Introduction
DDGS feed is the trade name of protein feed in distiller's grains, that is, dry distiller's grains containing soluble solids. In the process of fermenting corn to produce ethanol, the starch is converted into ethanol and carbon dioxide, and other nutrients such as protein, fat, fiber, etc. are left in the distiller's grains. At the same time, due to the action of microorganisms, the content of protein, B vitamins and amino acids in distiller's grains is higher than that of corn, and it contains unknown growth-promoting factors generated during fermentation.
There are two types of corn distiller's grains protein feed products on the market: one is DDG (Distillers Dried Grains), which is a feed obtained by simply filtering corn alcohol grains, drying the residue, discharging the filtrate, and drying the residue alone; the other is DDGS (Distillers Dried Grains with Solubles), which is a feed obtained by drying and concentrating the filtrate and then mixing it with the residue. The latter has significantly higher energy and total nutrients than the former.
Since the protein content of DDGS is above 26%, it has become a new type of protein feed raw material widely used by feed manufacturers at home and abroad. It is usually used to replace soybean meal and fish meal in livestock and aquatic feeds, with an addition ratio of up to 30%, and can be directly fed to ruminants.
2. Scope of application:
Corn DDGS (dry distiller's grains high protein) feed mainly refers to the symbiotic products formed by low-temperature drying of the remaining fermentation residues after corn seeds and selected yeast are mixed and fermented to produce ethanol and carbon dioxide in fuel ethanol factories with modern technology and equipment. In the process of producing ethanol, 2/3 of the starch in the corn seeds is fermented to form ethanol and carbon dioxide, and the other 1/3 forms symbiotic products. Since these symbiotic products have a high protein content, they are called protein feed. DDGS consists of DDG (Distillers Dried Grains) and DDS (Distillers Dried Soluble Soluble Distillers Grains Filtrate), which contains about 30% DDS and 70% DDG.
3. Dosage:
Poultry:
DDGS is an excellent source of essential fatty acids and linoleic acid. It can be used with other feeds to feed breeders and laying hens. DDGS lacks lysine, but the first limiting amino acid for poultry is methionine for feather growth. All DDGS products are excellent sources of methionine. The maximum dosage of DDGS in different poultry diets is: 2.5% for broilers, 5% for fattening broilers, 15% for laying hens, 20% for breeders, 5% for young hens, 5% for ducks, and 5% for fighting cocks.
Pigs:
DDGS feed can prevent pig intestinal digestive diseases and inhibit pathogens in the feed itself. DDGS has a high effective phosphorus content and a very low calcium content, which requires other mineral raw materials to supplement. It is rich in B vitamins and vitamin E, but has a very low lysine and tryptophan content, which must be supplemented. Corn DDGS is an excellent source of energy, protein and other major nutrients required by pigs at different growth stages. The maximum dosage of DDGS in different pig diets is: 20% for piglets (7 kg ~ 12 kg) and growing pigs (12 kg ~ 50 kg), 20% for fattening pigs (50 kg ~ 100 kg), 50% for pregnant sows, 20% for lactating sows, 50% for boars, and 20% for gilts. Improper use of DDGS will affect the palatability of the feed. It has a strong smell of alcohol when it is just shipped from the factory. When used in the production of pig feed, adding 5%-6% will cause the palatability of the feed to decrease, but after a period of storage, the irritating smell will be significantly weakened and the palatability will be improved.
Beef cattle:
DDGS is used in beef cattle feed. Its advantages are: improving rumen fermentation function, providing rumen protein, converting fiber into energy, strong palatability and food safety, and is an excellent source of minerals such as phosphorus and potassium. Beef cattle production experiments show that the net energy of fresh DG, fresh DGS and DDGS is 96%, 102% and 80% of that of flaked corn, respectively. Fresh or dried DGS can reduce rumen acidosis because fat and effective fiber in fresh or dried DGS replace soluble carbohydrates and starch, which helps maintain the balance of rumen microecology and stabilize rumen pH. DDGS is unique in terms of rumen-passing protein, excellent palatability and safety of effective fiber. The dosage in milk replacer is 20%; the dosage in milk supplement is 20%; the dosage in fattening beef cattle is 40% of the total dry matter intake; the dosage in replacement heifers is 25% of the total dry matter intake.
