Detailed Explanation of Key Points on Seed Sowing and Seedling Raising Techniques for Schisandra chinensis
1 Seed collection After late July, seed selection can begin in artificially cultivated gardens. The selection standard is to designate fruit-bearing trees with clusters longer than 8 cm, average berry weight above 0.5 g, and early berry coloring as seed collection trees. Harvest the fruit in mid-to-late September, pile and ferment for a few days, then select by water, skimming off shriveled

What should be noted before planting Sichuan lovage (Ligusticum chuanxiong)?
Sichuan lovage (Ligusticum chuanxiong) uses its root as medicine. People use it to make tea, which is mellow and tasty, cools and quenches thirst, and has effects such as dispelling wind and relieving pain, and promoting qi and blood circulation. 1. Cultivation method. Sichuan lovage is propagated by stem. Before planting, the soil should be deeply plowed, and for every 667 sq m use 120 kg of phosphate fertilizer, mixed with 1500 kg of farmyard manure as base fertilizer, then harrow fine and level, and make beds. When planting, select healthy stem nodes of uniform size, uniform thickness, and free of pests and diseases as seed sprouts, remove the upper tip, cut into small pieces of about 3 cm, each piece with one node disk, with 1.6 cm extending on each end of the node disk. After cutting, place them in a sunny, wind-sheltered, moist place, and soak the seeds with a 1000-fold dilution of carbendazim. You can also spray with a 150-fold dilution of 25% wettable phoxim, or dip them in 1:10 garlic juice, to control underground pests such as cutworms. Then pile them up and cover with gunny sacks. After 3-5 days, when white sprouts emerge from the node disks, they can be planted.

Comprehensive Control Methods for the Peach Borer Moth in Peach Cultivation
The peach borer moth larvae bore into and feed on peach fruit, causing gumming; the fruit discolors and drops, or the interior becomes filled with insect frass, making it unfit to eat, and this has a great impact on both yield and quality. I. Occurrence pattern. In Shandong, this pest occurs in 2-3 generations per year, mainly overwintering as mature larvae in cocoons inside damaged mummified peaches, bark crevices, gaps among loose stones in embankments, chestnut burs, sunflower heads, castor seeds, and corn and sorghum stalks, with a small portion overwintering as pupae. In Shandong, the first moth emergence of the overwintering generation occurs in mid-May, with the peak in early to mid-June; most eggs of the 1st generation are laid on early-maturing peach varieties, with the most eggs laid on the ventral (belly) side; the newly hatched larvae appear in mid-to-late June and mainly damage early-maturing peach fruit, boring into the fruit to feed; mature larvae spin cocoons and pupate at the stem cavity of damaged fruit and in bark crevices. The 1st-generation adults begin emerging in early July, with the peak from late July to early August; adults are highly selective in egg-laying, basically laying eggs on late-maturing peach varieties and pomegranates; newly hatched 2nd-generation larvae are found in mid-to-late July, with the peak in early to mid-August; by late July, larvae are already found maturing and pupating. The pupation peak is in mid-to-late August. As late-maturing peaches begin to be harvested, adults then move to other crops to lay eggs and continue causing damage.

Experience in achieving high yield and high quality by covering greenhouse peaches with old film
Peach trees are light-loving fruit trees and are sensitive to light; when light is insufficient, the photosynthesis of the leaves cannot proceed normally. In places with sufficient light, flower buds are numerous and plump, and fruit quality is good; in shaded places, flower buds are shriveled and fruit quality is poor. Covering greenhouse peach trees with old film will cause
