Topping: Topping is usually done from August to September. The method is to cut off the shoots of the new shoots and leave them 20 cm long. After the second shoots germinate, cut the shoots to leave 20 cm. Saplings can be pinched off branches with nails.
Twisting tip: Twisting tip can be performed simultaneously with topping. The method is to twist the semi-ligninized branches (20~30 cm long) in the direction opposite to their growth direction. It should be noted that the speed of twisting the shoots should be slow, and pay attention to the toughness of the branches to prevent twisting the branches. This method can control the growth of new shoots and strengthen the accumulation of photosynthetic products in the tree.
Curved branches: The curved branches are usually carried out in July to August, so that the new prosperous branches grow downward or left and right under the action of external force, and can also be tied to the branches of themselves or other branches to change the growth direction. Coil the branches in a circle, but do not break them.
Girdling, girdling, and upside-down skinning: Peel off the phloem of the branches, which is called girdling. Cuts only one ring of the phloem. Those who do not strip the skin are called circumcision. Put the peeled bark upside down and insert it into the original peeled place. The bandage is healed, which is called inverted sticking. These measures are all measures taken during the growing season to overgrown branches.
Eliminate long branches: Thoroughly pruning the long branches can not only improve the ventilation and light transmission of the fruit tree itself, increase the light, but also strengthen photosynthesis, reduce the useless consumption of nutrients, and increase the accumulation of tree camp. Note that the cut should be flat, without leaving a post, and avoiding new branches.
There are "five taboos" for fruit trees in summer
Sparse shoots are too early and too heavy. Thinning the shoots too early and too heavily will cause the leaves to form flower branches and germinate again, which will affect the formation of flower buds. At the same time, it will reduce the photosynthetic accumulation and affect the growth of the tree. The thinning should be carried out after the spring shoots stop growing. Up to about 30% is appropriate.
Open the branch too early. Too early to open the branch angle will lead to poor effect on the back and flower formation. For the new shoots to be used, the branches can be taken during semi-ligninization; for the main side branches with small angles, they should be opened in autumn.
Consecutive twisting tips. Consecutive twisted shoots affect the light. Generally, there are 3 to 5 twisted shoots on the same main branch. The advantages of the back can be used to form flowers, and the rest should be removed.
Re-topping. Heavy topping will promote re-growth, poor light transmission, poor flower formation, should be used sparingly.
Remove the auxiliary shoots of the fruit stand. Thinning the secondary shoots of the fruit stand will affect the fruit swelling, so the secondary shoots of the fruit stand should be thrown away to facilitate the supply of nutrients to the nearby fruit.

Amino acid are organic acids containing amino groups, which are the basic units of proteins. There are more than 20 kinds of amino acids that constitute proteins, which are often divided into essential amino acids and non-essential amino acids according to their nutritional needs for pigs and chickens. In pigs, chickens can not be synthesized, or can be synthesized, but the speed and quantity of synthesis can not meet its normal growth needs, so must be supplied by the outside world of amino acids, called essential amino acids. So far, the essential amino acids that have been widely used in the breeding industry are methionine and lysine
Efficacy and function of amino acid for Poultry and veterinary use:
First, Feed Amino Acid improve immunity
Amino acids are important nutrients in animals, which can improve the immunity of animals
Second, promote growth and development
Amino acids also have a positive effect on the growth and development of domesticated animals
Third, improve the efficiency of breeding
There is a certain relationship between animal amino acid intake and feed conversion rate. Reasonable strengthening of amino acid supply can improve feed utilization rate, reduce pollutant discharge and improve aquaculture efficiency
