种瓣及密度对大蒜产量的影响

THE INFLUENCE OF SEED CLOVES AND DENSITY ON YIELD OF GARLIC

采用二次正交通用旋转设计，进行了种辩大小与种植密度对大蒜产量影响的研究，建立了大蒜产量与种植密度及种瓣大小间的二元二次数学模型。通过模型解析得出，种植密度对产量的影响大于种瓣大小，但密度对单株产量的贡献为负值。通过计算机模拟试验，得出本试验条件下，获得３００００ｋｇ／ｈｍ２以上产量的种植密度为５２．９５～６３．４５万株／ｈｍ２、种瓣大小为４．９～７．０ｇ;;单株产量大于５０ｇ的种植密度为３４．０５～４．５５万株／ｈｍ２、种瓣大小４．９～７．０ｇ。

The experiment designed in quadritic perpendicularity and universal rotation recessionwith two factors of seed size and density in garlic. Accolding to the data obtained, a mathematicmodel describing the relation between the yield and seed size and density was established throunghcalculation with a electronic computer. When analysed, the model showed that the yield was influenced larger by density than by seed size, but the individual yield decreased with the density increased. Through imitation with electronic computer, the agronomic schemes for yields over30000kg/hm2 were that the plant density was 52.95-63.45×10' plant/hm2, the seed size was4.9-7.0g; the agronomic schemes for individual yields 50g were that the plant density was34.05-44.55×10 plant/hm2, the seed size was 4.9-7.0g.
