Detailed Explanation of New Techniques for Weed Control in Lily Fields
I. Weed Control After Sowing and Before Sprouting After lilies are sown and before sprouting, apply 100-150 ml of 33% pendimethalin emulsifiable concentrate per mu (1 mu = 1/15 hectare, the same below) mixed with 50-75 kg of water and spray evenly on the ground, with a residual effect lasting up to 50 days; apply 200 ml of 48% butralin emulsifiable concentrate per mu mixed with 50-75 kg of water and spray evenly on the ground, with a residual effect lasting about 30 days; in addition, for each mu of lilies, one may also choose 120-150 g of 50% herbicide No. 1 wettable powder, or 500 ml of 30% propachlor emulsifiable concentrate, or 60

What is the box tree pyralid, an insect found beside vegetable fields?
As spring warms and flowers bloom, insects begin to become active. During a recent science-and-technology outreach activity in the countryside, it was found that a pest called the box tree pyralid had begun to occur and cause damage on boxwood along the roadsides of the park. The box tree pyralid is one of the common pests on plants such as boxwood, small-leaved box, large-leaved box, littleleaf box, Chinese box, spoonleaf box, Korean box, and holly, and it occurs in Shanghai and other provinces and cities. In Shanghai it has 3 to 4 generations per year, with severe overlapping of generations. It usually becomes active in March in spring, begins pupating in mid-April, begins emerging in late April, and the first-generation lar

Planting Techniques for Intercropping Shrubs in Southern Magnolia Fields
In the first 3 years of southern magnolia seedling growth, to offset the drawbacks of large initial investment and no profitable output from field-planted trees in the early stage, small shrubs such as littleleaf boxwood, golden-leaf privet, and red-leaf barberry can be intercropped. During the first 3 years of intercropping small seedlings, 6000-7000 plants per mu at an average of 0.5 yuan per plant can yield more than 3000 yuan in income. After the 4th year, the southern magnolia has grown to 5-6 cm, and can then be sold selectively at about 80 yuan per plant. From then on, annual sales all generate income. Cultivation points: southern magnolia 1-year

Technique of Intercropping Small Shrubs in Southern Magnolia Fields
In the first 3 years of southern magnolia seedling growth, to offset the drawbacks of large investment and no profitable output from planting trees in open fields in the early stage, small shrubs such as Japanese boxwood, golden-leaf privet, and red-leaf barberry can be intercropped. During the first 3 years of intercropping small seedlings, at 6000-7000 plants per mu, averaging 0.5 yuan per plant, more than 3000 yuan in returns can be obtained. After the 4th year, the southern magnolia has grown to 5-6 cm, and at this point they can be sold selectively, at about 80 yuan per plant. From then on, selling each year yields returns. Cultivation points: when planting 1-year-old southern magnolia seedlings, plant spacing 1.2-

Key Technical Points for Interplanting Small Shrubs in Southern Magnolia Fields
In the first 3 years of southern magnolia (Magnolia grandiflora) seedling growth, to offset the drawbacks of large initial investment and no profitable output from field-planted trees in the early stage, small shrubs such as Japanese boxwood (Buxus microphylla), golden privet (Ligustrum sinense 'Variegatum'), and red-leaf barberry (Berberis thunbergii) can be interplanted. During the first 3 years of interplanting small seedlings, at 6000-7000 plants per mu, averaging 0.5 yuan per plant, a return of over 3000 yuan can be obtained. After the 4th year, the southern magnolia has grown to 5-6 cm, and can then be sold selectively at about 80 yuan per plant. From then on, annual sales all generate income. Cultivation points: when planting 1-year-old southern magnolia seedlings, plant spacing 1.
