The Best Time to Harvest Lilies and Harvesting Methods
Cut flower harvest: When the petals of the first flower on the inflorescence show their natural color, it can be cut. When bulb harvest is not a consideration, cut from the base of the stem to increase the length of the flower stem. If the bulb is to be used or seeds are to be saved, leave 10-20 cm of stem, while retaining a certain number of leaves, and apply additional fertilizer appropriately to promote bulb growth. Bulb harvest: The harvest period can begin once the aboveground part has died off, though the timing varies from place to place. Dig out the bulbs, remove the stems, spread them out to dry (do not sun-dry), and for those being saved for seed, do not damage the root system.

How to calculate material quantities, seed purchase quantities and investment for first-time Gastrodia elata planting
1. Sexual reproduction: to plant 60 sq m, you need broadleaf tree branches (fresh) 3000-4000 jin (400 yuan), broadleaf tree leaves 100 jin (20 yuan), Armillaria mellea spawn 100 bottles (300 yuan), germination fungus 100 bottles (800 yuan), Jianma tubers 10 jin (180 yuan), total investment 1700 yuan. 2. Asexual reproduction: to plant 60 sq m, you need broadleaf tree branches (fresh) 3000-4000 jin (400 yuan), broadleaf tree leaves 100 jin (20 yuan), Armillaria mellea spawn 100 bottles (30

When is the best time to harvest Gastrodia elata capsules
After the flowers of Gastrodia elata are pollinated, the ovary gradually enlarges, and the capsule is light brown or pink, elongated ovoid, with 6 longitudinal ridges. Each capsule contains 10,000 to 50,000 seeds, with a maximum of 80,000 seeds. The seeds are tiny. They are powder-like, and their size and shape are difficult to distinguish with the naked eye. Observed under a microscope, mature seeds are spindle-shaped, 0.6 to 1 mm long and 0.14 to 0.2 mm wide. The embryo is 170 to 180 micrometers long. The seed coat is white and semi-transparent, wing-like, composed of parenchyma cells, with no endosperm inside; the embryo is light brown or dark brown. Those without dark brown color are immature seeds, called blighted seeds. The transverse and longitudinal sections of mature Gastrodia elata seeds appear elliptical and circular, respectively, under a microscope.

The most suitable planting time for Gastrodia elata and its impact on yield
Gastrodia elata is best planted during its dormant period. Winter planting in October to November and spring planting in March to April both give relatively good results. Gastrodia elata is generally not planted in summer, because this is precisely its growing season; digging it up at this time disrupts the relationship between Gastrodia elata and Armillaria mellea, and even if it barely survives, the results are very poor. Choosing an appropriate cultivation time is one of the important measures for increasing Gastrodia elata yields. The most suitable cultivation time is October to November (called autumn-winter planting), followed by February to March (called spring planting), and the worst is June to July

When is the best time to plant lilies?
In the Central Plains region, mid to late September is suitable; in high-altitude cold regions it can be moved up appropriately. Too late, and there will be too little rooting before winter, so growth will not be vigorous in early spring and emergence will be poor; too early, and the soil temperature is too high, making the bulbs prone to disease and rot, causing missing plants and weak seedlings. The general principle is to plant earlier rather than later. The best planting time is when the daily average temperature is around 20°C, with no high temperatures above 32°C, and on a sunny day after rain.

Sweet potatoes turn into feed, saving costs and increasing efficiency at the same time
1. Tuberous roots: each unit of fresh sweet potato is equivalent to 0.3 corn units. It is an excellent succulent feed and also a very good energy feed. All kinds of livestock like to eat it, and it is most suitable for feeding meat pigs. The method is to boil it, mix 15-20 kg of cooked sweet potato with 1 kg of concentrated feed (crude protein >= 34%), stir evenly and feed to meat pigs. The effect is the same as a complete compound feed, but the feed cost is much lower than compound feed. Feeding sweet potato alone or feeding it raw has a poor effect. Tuberous roots that are rotten or have black spot disease should be buried deep in a pit, and it is strictly forbidden for humans and livestock to eat them

Sweet potato starch is in high demand in the market, and timely processing yields high returns.
Sweet potato starch occupies an increasingly important position in people's daily diet. Potato-based chemical products have now become the main raw materials for chemical products such as lactic acid, citric acid, disposable tableware and degradable agricultural mulch film. It is understood that the current price of refined white potato starch has risen by nearly 10% compared with last year, and the reason for this price trend is undoubtedly the supply-demand gap for sweet potato starch. Relevant data show that at present, the demand for sweet potato starch in the domestic market alone is more than 1 million tons, while the production volume is far less than this number.

September is exactly the right time to plant honeysuckle
Cutting propagation: Carry out cuttings in early spring before the new buds sprout, or in autumn from September to October. The seedbed should be close to a water source, with the soil deeply plowed and plenty of base fertilizer applied. Make raised beds 1.3 m wide. Select robust, pest- and disease-free 1- to 2-year-old branches, cut them into cuttings about 33 cm long, and remove the lower leaves. Then open horizontal trenches on the bed at a row spacing of 27-30 cm, with the trench depth depending on the length of the cuttings. Place 10-15 cuttings in each trench, bury 2/3 of each cutting in the soil, and firm the soil after filling.

Garlic sowing time should not be advanced; mastering the right sowing time is key
Garlic prefers cool conditions and has a dormant characteristic. If sown too early, the emergence time is prolonged, and after emergence the temperature cannot drop, so the leaves tend to turn yellow and form weak seedlings, ultimately affecting quality and yield. If sown too late, before overwintering the seedlings are small and have weak cold resistance, and the following year they easily form large-headed garlic. By summarizing the experience of growers and the author's trials, it is recommended that garlic in our province be sown in late September. At this time the garlic dormancy period has passed, and 13 days after sowing the seedlings can emerge uniformly. After emergence, the seedlings are in the cool autumn season, which is favorable for their growth, and before overwintering they can grow enough 6 leaves, with enhanced cold resistance.

How to control the Euonymus leafroller moth at the right time?
The Euonymus leafroller moth, also known as the Euonymus moth, is one of the earlier leaf-eating pests to harm garden plants. After several years of observation, the author found that in the Xi'an area its larvae appear in late March, mainly harming plants such as Euonymus japonicus (evergreen euonymus), Euonymus bungeanus (winterberry euonymus), and Euonymus fortunei (climbing euonymus). In severe cases they eat all the leaves, affecting the ornamental effect. When low-instar larvae are found causing damage, spray evenly with 50% phoxim emulsifiable concentrate or 40% omethoate emulsifiable concentrate at 1000 times dilution, or with 2.5 deltamethrin emulsifiable concentrate at 2000 times dilution; the control effect is very good.
