What are the key points of summer management techniques for jujube trees?
1. Increasing fruit set rate (1) Remove root suckers. Root suckers consume a large amount of nutrients, and any root suckers found should be dug out promptly. (2) Remove buds and pinch off tips. Control the sprouting of jujube heads; all new buds with no space in the inner canopy should be removed, leaving only a few jujube hanging fruiting shoots. (3) Girdling. When 30%-40% of the flowers have opened, trunk girdling can be carried out. The width of the girdle should be 1/10 of the trunk diameter. It should be done without damaging the xylem, and the girdle cut should have no ragged edges. After girdling, apply a 200-fold solution of carbendazim and seal it with clear adhesive tape. (4) After girdling, spray the plant with 2.5-3.5 kg of ice in the morning or afternoon. Alternatively, during the flowering period of jujube trees, spray 5 ppm of 2,4-D or 10 ppm of sodium naphthaleneacetate solution.

What are some practical methods to increase the fruit-setting rate of jujube trees?
For jujube trees to be high-yielding, fruit setting is the most critical. Management depends on technique; for fruit setting, find the patterns. The flowering period must be seized firmly, and the secrets must be kept firmly in mind. 1. Flowering period The flowering period of jujube trees is relatively long, generally 35 days, that is, from May 25 to June 30. The flowering period is divided into the early flowering stage, full flowering stage, and late flowering stage. Around June 8

How can the boll-setting rate be increased in cotton cultivation?
Types of square and boll shedding in cotton include physiological shedding, shedding caused by pests and diseases, and shedding caused by mechanical damage. As for the causes of physiological shedding: first, excessive application of fertilizer and water causes excessive vegetative growth, with nutrients consumed too heavily in the early stage and supply falling short of demand in the later stage; second, excessive planting density in the cotton field causes severe shading by branches and leaves, reducing light, weakening photosynthesis, and decreasing the nutrients produced; third, some cotton fields are deficient in boron, causing cotton to flower but not set fruit; fourth, high temperature and drought, insufficient fertilizer and water, or excessively high temperatures cause cotton pollen sterility; fifth, frequent rainy weather leads to poor pollination. As for pest and disease damage, inadequate control of cotton mirids, cotton bollworms, Fusarium wilt and Verticillium wilt can easily lead to massive square and boll shedding. As for mechanical damage, it is mainly caused by improper operation during field management. In addition, in the past two years, blind application of herbicides has occasionally caused square and boll shedding.

How can the sugar content of thick-skinned melons grown in solar greenhouses be increased?
In recent years, the area devoted to cultivating thick-skinned melons in solar greenhouses has grown larger and larger. Because growers single-mindedly pursue yield, the sugar content of thick-skinned melons is low and prices have fallen. Therefore, how to increase the sugar content of thick-skinned melons has become a key technical measure in cultivation.

What are the key technical measures for increasing yield in the late growth stage of corn?
To achieve high corn yields, the following four key techniques should be carried out in the late growth stage. 1. Pull out barren stalks. After the booting stage of corn, time should be taken promptly to pull out the barren plants that have weak growth, slender stalks, and either no ears or ears that cannot grow large and do not silk, pollinate, or set seed.

Method for Soaking Wheat Seeds in Biogas Slurry to Boost Yield
Biogas slurry contains a variety of active, resistance-related and nutritional substances. Soaking seeds in biogas slurry can promote the metabolic activity of wheat seeds, making wheat seedlings emerge evenly, with well-developed root systems and vigorous growth, enhancing cold and disease resistance, and increasing wheat yield. According to trials, soaking wheat seeds in biogas slurry

How to regulate peanut flowering with chemical control? Practical measures explained in one article
Yield-increasing ling has the effect of promoting the movement of nutrients within the plant, accelerating cell differentiation, preventing shedding, preserving flowers and fruits, promoting grain filling and early ripening. During the peanut flowering period, spray the leaves 1~2 times with a 10~30×10-6 solution; the rate of blighted pods is reduced by 10%~20%, and per 667 sq m

Adopting the "three protections" technique in peanut cultivation significantly increases yield
1. Preventing excessive vegetative growth. For peanut fields with relatively high soil fertility, good water and fertilizer conditions, and vigorous plant growth, when growth is too vigorous and excessive vegetative growth occurs, spraying hormones, namely plant growth regulators, can inhibit vegetative growth, promote reproductive growth, and coordinate the relationship between vegetative growth and reproductive growth.
