Practical experience sharing on growing plums in greenhouses
In order to explore the early fruiting and early high-yield techniques of cultivating plums in greenhouses, our station conducted experimental research from 1997 to 2000. The greenhouse was covered in the winter of the second year after planting, and in 2000 a 4-fen plot greenhouse produced 1000 kg of plums. The output value was more than 10,000 yuan, and the maturity period was about 60 days earlier than open-field cultivation. Through the experiment

How to prevent and control insects boring inside plum fruits?
Speaking of plums, I think everyone is familiar with them. I remember that when I was a child, there were several plum trees right at our doorstep, but back then our family did not need to manage the plum trees much, and they still bore plenty of fruit every year. But if you want to grow plums that are both tasty and good-looking,

How to Control the Alternate Bearing of Plum Trees? Practical Cultivation and Management Methods
1. Reasonable pruning to regulate tree vigor. On-year trees should be pruned early (before the onset of winter) and heavily. Remove dead branches, residual branches, slender branches, scorched-tip branches, diseased and pest-infested branches, and excessively dense, crossing branches. Do more heading back to stimulate shoot growth; for vigorous branches and competing branches, cut back hard, removing 2/3 to 3/4 of the branch or leaving only 3 to 5 buds. Thin flower buds early, prune away excess flowering branches, and reduce the fruit load. Off-year trees should be pruned late (around the beginning of spring), keeping flowering branches and thinning out non-flowering vegetative branches. Leave branches unpruned or bend them down to moderate tree vigor, retain as many flowers and fruits as possible, and increase the fruit set.

Key Points of Early High-Yield Cultivation Techniques for Peach Trees
In the spring of 2002, a peach orchard of 0.67 hm2 was established in Yutian County, Tangshan City, with the cultivars Shijiwang Tao and Shijihong Tao. In 2003, the average yield per 667 m2 was 890 kg; in 2004 it reached 2400 kg; and in 2005, 2006, and 2007 the yield stabilized at 3500 kg. The specific management techniques are described below.

Spring Pruning Methods and Technical Key Points for Densely Planted Jujube Trees
The small canopy open-center layered form has a trunk height of 80-90 cm. Suppress the secondary branches on the trunk and promote the development of 3-4 jujube heads (main shoots), so that the topmost jujube head extends upward to become the trunk extension branch, and the 2-3 jujube heads below are trained as main branches. In the second year, cut back the trunk branch leaving about 60 cm, and remove the

How to remedy mango "false bearing"? Detailed explanation of prevention and treatment methods
We often see: when mango trees grow too vigorously, they show low yield or fail to set fruit. This is because vegetative growth dominates, while reproductive growth is at a disadvantage. In response to this situation, effective measures should be taken to solve the problem of mango trees not setting fruit or setting few fruit (that is, false

How to prevent early flowering in mango? Key points for planting management
Mango is an evergreen fruit tree that consumes a large amount of water and nutrients. If it encounters long-term drought weather, combined with improper water and fertilizer management, once the accumulated temperature is sufficient, flower bud differentiation will be rapid, and early flowering will occur, making it vulnerable to low-temperature cold and overcast weather; the flowers cannot be pollinated, the fruit-setting rate is low, causing reduced yield or total crop failure

What are the technical measures for flower and fruit retention in mango?
The flowering and fruit-setting period of mango is an extremely critical period in mango production management. The management measures during the flowering and fruit-setting period include the following aspects: 1. Training of flowering shoots. About 2 months before flower bud differentiation, remove overly dense branches, shaded weak branches and diseased and pest-infested branches, leaving only 1-2 shoots per branch, which can increase the light penetration of the canopy, help concentrate nutrients and create good ventilation and light conditions, promote flower bud differentiation and prevent the occurrence of pests and diseases.

How to Propagate Figs: A Detailed Guide to Common Propagation Methods
Cuttings, layering, sowing and other methods can all be used for propagation, but in production practice asexual propagation is commonly used; sexual propagation is only used in breeding work. (1) Cutting propagation: Fig branches readily produce adventitious roots, so cuttings are mostly used for propagation in production. Mid-February to late March

High-yield Cultivation Measures and Technical Points for Melons
I. Sowing Period For spring protected cultivation, the temperature inside the greenhouse should be stable above 10°C at transplanting time; counting back 30-35 days from this point is the optimal sowing period. II. Raising Strong Seedlings 1. Preparation of nutrient soil: decomposed barnyard manure, horse manure (or chicken manure), and sieved field topsoil, in a ratio of 3:2:
