Peach blossom and fruit management technology
First, the implementation of long-range pruning technology blindly picking up the heart, will lead to the backbone of the backbone of the branches more leggy branches, new shoots are also more branches, crown ventilation and poor light. Timely sparse shoots with dense shoots and leggy shoots, especially for a large number of sprouted shoots drawn from latent shoots or adventitious shoots on the perennial branches of the canopy, are treated as early as possible. To use the updated, leave 10-15 cm topping or cutting tip, which is beneficial to the renewal and rejuvenation of the lychee group, without affecting the ventilation and light transmission and fruit surface coloring.
Second, a reasonable fertilization irrigation water topdressing before flowering fertilizer, strong fruit fertilizer and pre-harvest fertilizer, and timely irrigation combined with fertilization, increase tree nutrients, in order to facilitate fruit development, lay the foundation for increasing income and increase production.
Third, improve the quality of pollination flowering spray 0.3% borax solution or before and after flowering Shuofeng "481" 500 times the liquid, improve pollination fertilization and flower and young fruit ability to resist the variable weather. For pollen-free or pollen-free varieties, artificial pollination or release of bee and wall bee pollination should be carried out at the flowering stage in order to increase the fruit setting rate.
Fourth, timely fruit thinning and fruiting For self-cultivation rate of high varieties, should be sparsely flowering fruit thinning, the sooner the better; for no pollen or self-flowering rate of low varieties, not sparsely thinning only fruit. Thinning fruit should be completed within 2 weeks after flowering. Try to choose the fruit with a length of 5-30 cm and a thickness of 0.3-0.5 cm. Each long fruit branch chooses to retain 2-3 fruits, 1-2 fruit of middle fruit branches, and 2-3 branches of short fruit branches to choose 1 fruit, and the fruit spacing is kept between 15-20 cm.
Fifth, the implementation of fruit bagging fruit bagging can significantly improve the fruit surface finish, increase color, reduce pest and pesticide residues, and prevent cracking and sunburn. Late peach varieties in particular should pay attention to fruit bagging. Immediately after the fruit set, the bag was bagged, and the insecticide was carefully sprayed before the bag was bagged, and the bag was removed 3-5 days before the harvest.
Sixth, to strengthen the prevention of pests and diseases After flowering on the 15th, it is best to spray once every 10-15 days a bactericide, prevention and treatment of bacterial perforation, anthrax, plastic gum disease, etc., in late April to mid-August, spray once a month Insects, acaricides, control peaches, spider mites, peach aphid, peach borer and leaf miner and other pests.
Selenium-enriched Rice grows selenium-rich rice by selenium supplementation when rice is grown. It is a functional agricultural product and is a food rich in selenium with high nutritional value.
Selenium
is an indispensable trace element to maintain the normal function of
the human body. Selenium deficiency in the human body can lead to
various diseases. Modern scientific research
proves that selenium has anti-oxidation, enhances human immunity,
effectively removes harmful garbage, promotes human health, and delays
aging.
