The correct method for broadcasting compound fertilizer during the rice stem elongation stage
During the rice stem elongation stage, topdressing is generally carried out 1 to 2 times. In previous years we used urea, but this year we switched to a high-tower granulated fertilizer. This is a compound fertilizer with high nitrogen and low phosphorus and potassium. The fertilizer granules are round and smooth on the outside, with holes inside, and have a relatively low specific gravity. Before fertilizing, we first drained the flooded water, then broadcast the compound fertilizer granules on the soil surface, and immediately let water back into the field. After the water layer was full, we found that some fertilizer granules appeared on the water surface. These floating granules were blown to one side by the wind, and some stayed in the sheltered corners.

Off-season cultivation of edible fungi is highly profitable, with broad market prospects
So-called off-season cultivation refers to cultivation carried out in seasons when normal growth is not possible. In edible fungi production, this is essentially a matter of timing, that is, cultivation carried out in natural seasons when normal production is not possible through improved facilities and equipment, artificial regulation of conditions and other auxiliary means, and it can also achieve production results similar to those of normal-season production; for example, the relatively typical summer cultivation of enoki mushroom (Flammulina velutipes) and winter cultivation of straw mushroom, and so on. For example, the low-temperature variety enoki mushroom should fruit from November to February, but with facility-based automatic controlled cultivation

How to control broadleaf weeds in potato fields?
(1) Crop rotation: Rotation reduces the density of associated weeds, changes the dominant weed community in the field, and lowers the weed population in the field. (2) Plowing and turning: After the soil is plowed and turned multiple times, perennial weeds such as Ixeris denticulata are buried underground, causing the weeds to gradually decrease or decline in vigor, thereby inhibiting their growth and achieving the purpose of weed control. (3) Inter-row cultivation and hilling: This measure not only controls weeds but also has effects such as deep loosening and water storage and moisture conservation. For example, for open-field potatoes, inter-row cultivation is generally carried out the first time when the seedlings are about 10 cm tall,

Potato No-Till Broadcast Placement and Mulch Cultivation Technique
Saving labor costs of 150 yuan/mu and increasing production efficiency by 37.6%. Potato no-till broadcast placement and mulch cultivation is worth promoting. No-till broadcast placement with full-season rice straw mulching is a brand-new complete potato planting technique today. It refers to opening furrows and dividing beds according to certain specifications on unplowed land, applying basal fertilizer in strips on the bed surface, placing seed potatoes at a certain density in the fertilizer-free zone between two rows of fertilizer, and then covering the whole period with rice straw. Because this method is simple to operate, saves labor and effort, and also allows potatoes to be picked in batches and sold according to price, it improves planting efficiency.

What potato preservation techniques are used abroad?
1. Anti-browning, sterilization and preservation. The agents include sodium hypochlorite, calcium hypochlorite, ascorbic acid, etc. For anti-browning of potatoes, the most effective concentration of sodium hypochlorite is 17.5mg/L soaking solution, pH value 4, soaking time more than 5 minutes; the most effective concentration of calcium hypochlorite is also 17.5mg/L, but the color-protecting effect of soaking is not limited by the pH value of the solution. The most effective concentration of ascorbic acid for color expansion is 0.3%. 2-Phospho-ascorbic acid is a newly developed non-sulfur color expansion agent with good effects. 2. Preservation and freshness keeping. Pre

The development prospects for Butterfly Bush are extremely broad
Butterfly Bush is the most popular landscaping tree species in Europe and America, and is highly suitable for promotion in North China, Central China, East China, and parts of Northeast and Northwest China. In terms of landscaping effects, this tree species has many advantages. It is a perennial, fast-growing, semi-evergreen shrub with grayish-green leaves that are large and opposite, about 25 cm long. From summer to late autumn, it continuously blooms with lush panicles, the inflorescences about 40 cm long, in diverse colors including purple, blue, pink, white, and yellow. The flowering period lasts up to 6 months, which can compensate for the scarcity of blooming plants in summer. The flowers have a strong fragrance, attracting many

It is light-demanding but tolerant of shade, prefers a warm, humid climate, and is suited to slightly acidic to slightly alkaline or calcareous soils. It can also grow in clayey soil with a salt content of 0.2%, can withstand low temperatures of -12°C, and is not tolerant of poor, thin soils. It is deep-rooted with well-developed fibrous roots, grows quickly, has strong sprouting ability, and tolerates pruning. It is not strict about climate, but is best planted in humid, sheltered, sunny spots, and grows especially well in deep, fertile soil rich in humus.

How to propagate broadleaf privet? Detailed propagation techniques
I. Seed propagation 1. Seed selection: In North China, late November to mid-December is the suitable period for seed collection. Choose trees with strong vigor, good form and strong resistance as mother trees. Carry out collection on a sunny afternoon, selecting seeds with high maturity, plump grains and no pests or diseases. After collection, dry them in a cool, ventilated place in the shade; avoid direct sunlight. 2. Soil mixing and land preparation: Select 2 parts fertile sandy loam with a pH of 6.7 to 7.0, 1 part high-quality peat soil, and 1 part field soil, then add 1.5 kg of diammonium phosphate and superphosphate
