How to fertilize hawthorn?

Fertilization is a very important step no matter what tree is planted. Improper handling may affect the growth of trees. Therefore, there are clear requirements for what season, what climate to apply fertilizer, and how much fertilizer to apply, even if trees There is a strong ability to survive and adapt, no fertilizer to provide nutrients, it is also difficult to survive. So what are the requirements for fertilizing for hawthorn?

Method of fertilizing hawthorn

I. Fertilization of hawthorn soil

1. Fertilization period

(1) Top dressing before germination: More nitrogen fertilizer is needed from germination to flowering.

(2) Fertilization in the growing season: In July, nitrogen fertilizer and phosphorus and potassium fertilizers were used together. After the fruit was harvested in August, nitrogen, phosphorus and potassium fertilizers were combined with watering.

(3) Autumn application base fertilizer: long-term fertilizer, with autumn application as good.

2. Fertilization method

(1) Annular groove application: Dig a circular groove of thirty-four centimeters and a width of 15-45 centimeters at the outer edge of the tree to mix the surface soil with the base fertilizer.

(2) Cave application: Dig a cone with a tree roughly one meter away from the land, fill the dead grass, cover it with plastic cloth, and pour the top dressing inside.

(3) Radial ditch application: In the place 1 m away from the trunk, the length of a groove is dug to the outer edge of the canopy, and the fertilizer is poured into the ditch and covered with soil.

(4) Strip-shaped ditch application: Dig a long strip of ditch one foot away from the land, and pour the fertilizer into the ditch and cover it with soil.

3, the right amount of fertilization: saplings apply 40 to 80 kilograms per tree per year; the big tree applies 70 kilograms of organic fertilizer per plant per year, chasing urea 1.5-2 kilograms, and potassium sulfate 1 kilogram.

Second, the hawthorn leaf surface spray fertilizer

1. When spraying fertilizer, stagger the high temperature period. Choose to do the best before 10:00 am to 4:00 pm. The previous period is mainly sprayed with urea. In the latter stage, the actual spraying of potassium dihydrogen phosphate is better.

2, Hawthorn management in autumn and winter season: autumn Shi base fertilizer, good pruning in winter.

3, pest control: In autumn and winter, hawthorn larvae are more harmful, so remember to spray some anti-insect and disease-proof syrup, combined with fertilization, reduce pest and disease damage.

4, to prevent premature defoliation: timely watering, hawthorn leaves should also spray water, in order to enhance its growth capacity, reduce premature leaves.

The strong adaptability of hawthorn trees, combined with the correct fertilization methods at different times, will not be a problem for healthy growth. If properly cared for, it is possible to have a bumper harvest.

What is S-23?

S-23 demonstrates a markedly strong bond to androgen receptors

S-23 is an modern selective androgen receptor modulator (SARM) with the added interest in its potential for male hormonal contraceptive. It binds to the androgen receptor more strongly than older compounds such as Andarine with a Ki of 1.7nM, and in animal studies it showed both a good ratio of anabolic to androgenic effects, and dose-dependent suppression of spermatogenesis with spontaneous recovery after cessation of research.

Added value for research with pronounced suppression of spermatogenesis. Not for human consumption.

S-23 Function

S-23 not only boosted muscle mass, but also reduced fat mass, as studied. SARMs have a bit of a 'soft' image in the doping world. They don't stimulate muscle growth in the way that anabolic Steroids do, but many users say that they are safer.

There are no studies yet that confirm this suspicion. But that S23 is not one of the safer SARMs - we'd be willing to wager a bottle of BCAAs on that.

S23 halts the production of sperm in the testes. In fact it does this so well that the researchers suspect S23 might be a good candidate for a male contraceptive. If this is the case it would probably have to be part of a cocktail that also contains an estradiol analogue, the researchers discovered. The lab animals lost their libido when they were given S23 on its own, and only recovered this when they were given estradiol benzoate together with the S23.
