Detailed Explanation of Key Technical Points for Late-Stage Management of Rice in the Main Field
I. Water-Saving Irrigation Techniques During the rice growth period, water-saving techniques should be adopted for irrigation, with irrigation and drainage carried out according to the water requirements and characteristics of rice at each growth stage. These are mainly divided into deep-water greening, shallow-water tillering, deep-water booting and heading, and shallow-water ripening. During the greening stage, because the roots of the seedlings are damaged during transplanting and absorb little water while leaf transpiration is high, deep-water greening must be applied after transplanting to prevent physiological water loss, with a water depth of about 2-3 cm being appropriate. If the irrigation water is too deep, nutrient decomposition is slow, which is unfavorable for tillering; the booting and heading stage is the period of the greatest water demand in the entire life of rice

Methods and Technical Key Points for Controlling the White-Backed Planthopper in Rice
Damage symptoms: Adults and nymphs gather in colonies at the base of rice plants and pierce and suck the sap, causing the leaf tips of rice leaves to lose green and turn yellow, and in severe cases the whole plant withers and dies. Damage during the heading stage can also cause difficulty in heading, blighted panicles, or browning of the panicles, along with many empty grains and other damage symptoms. Morphological characteristics: Adults have two forms, the long-winged type and the short-winged type. The long-winged adult is 4-5 mm long, grayish yellow, with a rather narrow vertex projecting in front of the compound eyes; the face has 3 raised longitudinal ridges, with the ridges light in color and the grooves dark, black and white sharply distinct; in the center of the scutellum on the thoracic dorsum grows a pentagonal white or bluish-white spot; in females the

Key Technical Points and Management Methods for Autumn Potato Cultivation
Autumn potato refers to potatoes planted from early July to early August and harvested in winter (mid-to-late November). Its growth period is short, and the purpose of planting is to provide excellent seed potatoes for the main spring potato production. Therefore, autumn potato cultivation has relatively strict requirements for plots, seasonal timing, and other factors. The more successful cultivation techniques are as follows: 1. Plot selection. Autumn potato is suitable for planting in low-heat river valley zones, flatlands, and semi-mountainous areas at altitudes of 1600-2000 m with abundant natural resources such as light, heat, and water. The main suitable planting plots are: mid-August

Detailed Explanation of Key Technical Points for Autumn Potato Planting
Planting potatoes in autumn: the production period is short, harvest is quick, and returns are good. The following techniques must be carried out well. 1. Land preparation and fertilization. Choose sandy soil or sandy loam land or fields with loose soil for planting. First use farmyard manure, human excrement, or fermented cake fertilizer as base fertilizer, spread it on the ground, then plow, level, and open beds 1 m and 1.3 m wide. 2. Sprouting and sowing. Select seed tubers with no rot or injuries and about the size of a chicken egg, cut them crosswise and lengthwise into 4-6 pieces, each with an eye. After cutting the seed pieces, rinse them lightly with cold water, air-dry them,

Detailed Explanation of the Key Technical Points of Jujube-Grain Intercropping
1 Scientific Basis of Jujube-Grain Intercropping 1.1 Seize the time difference between the growth of jujube trees and intercrops to make full use of fertilizer and water resources. The jujube tree is a fruit tree that sprouts late, sheds its leaves early, and has a relatively short annual growth period. It generally begins to sprout in mid-April and sheds its leaves in mid-to-late October, while wheat is sown in late September and harvested in early June of the following year. The symbiotic period of jujube trees and wheat is about 80 to 90 days. From mid-May to early June is the period when wheat flowers, fills grain, and matures, mainly absorbing phosphorus and potassium fertilizer, with nitrogen fertilizer as a supplement. And the jujube tree is precisely in the period of growing leaves, differentiating young buds

Key Technical Points for Autumn and Winter Management of Pear Orchards
Autumn and winter is an important period when pear trees shed their leaves and enter dormancy. Strengthening the management of pear orchards in autumn and winter is beneficial to the growth, flowering and fruiting of pear trees the following year. 1. Rational fertilization: By the end of November, apply a deep autumn fertilizer to the pear orchard once, and the amount applied should account for more than 30% of the total annual fertilizer application, mainly organic fertilizers such as decomposed oil cake fertilizer, residue fertilizer, composted manure and human and livestock manure. The method is: at the drip line of the canopy of adult pear trees, dig 1-2 ring-shaped fertilization pits about 60 cm long and 25 cm deep and 25 cm wide, and apply 30-40 kg of decomposed human, livestock and poultry manure water fertilizer per tree.

Peach Tree Planting and Cultivation Methods and Key Technical Points
(1) Seedling raising and planting. For graft propagation, use wild peach rootstock; the seeds undergo stratification treatment and are broadcast sown in winter; bud grafting is done from June to August, or cleft grafting in early spring of the following year; the following winter the saplings can be lifted from the nursery. The planting spacing is 4 m x 5 m or 3 m x 4 m, with 500-840 trees planted per hectare. Planting can be done anytime from after leaf fall to before bud break. A peach orchard must not be continuously cropped, otherwise young trees will show noticeably weak growth, leaf chlorosis, new roots turning brown with many forks, and gumming on the branches and trunk. This continuous-cropping intolerance is more severe in sandy soil or soil with low fertility. The main cause is that the residual roots of the previous crop decompose in the soil

Processing Methods and Technical Key Points for Fox, Raccoon Dog and Mink Feed
Fur-bearing animals such as mink and foxes have well-developed canine teeth, a short digestive tract, a small stomach volume and no cecum, food passes through the digestive tract quickly, and their digestive glands secrete little amylase but more lipase. Therefore, their feed should be based mainly on animal feed, and in particular animal protein feed should account for a very large proportion of the daily ration. Thus, the feed processing and preparation methods for mink and foxes have distinctive characteristics, which are introduced below: 1. Material selection. Remove large pieces of fat from meat feed, remove the gallbladder and thyroid from livestock and poultry offal, and pick out lumps, impurities or foreign matter from dry animal powder feed and grain powder.

Key Technical Management Points for Artificial Snake Breeding
Snakes are animals with high medicinal value. Catching wild snakes is prohibited by national law, yet the market demand for meat snakes is astonishingly large. In the Guangdong market alone, the annual demand is conservatively estimated to have reached 7,500 tons. With wild snake resources severely insufficient and capture prohibited by law, a huge market vacuum for snakes has formed. To meet market demand and accelerate the promotion of factory farming, there is undoubtedly far-reaching socioeconomic significance. According to the experience of Dadongyang Snake Research Center, a cobra raised by factory
